This video discusses magnetism, magnetic fields, Ampere's Law, torque, solenoids, and physics problems. It explains the relationship between current and magnetic fields, the right hand rule, and how to calculate magnetic forces and torques in various scenarios. The video also covers the concept of magnetic dipole moments and the calculation of magnetic fields in solenoids. Key moments: 00:01 Magnetism involves attraction and repulsion between poles. Magnetic fields are created by moving electric charges, illustrated by the right-hand rule. -Illustration of magnetic field using the right-hand rule. The direction of the magnetic field around a wire can be determined by the direction of current flow and the curl of fingers around the wire. -Calculation of magnetic field strength. The equation B = u0 * i / 2πr is used to calculate the strength of the magnetic field created by a wire, where u0 is the permeability of free space. -Relationship between current and magnetic field strength. Increasing current increases the magnetic field strength due to direct proportionality. Decreasing distance weakens the magnetic field due to inverse proportionality. 08:03 Calculating the distance from a wire for a magnetic field strength involves using the equation involving current, magnetic field strength, and constants. Understanding the relationship between current, magnetic field, and magnetic force is crucial in physics. -Converting distance units from centimeters to meters is essential in physics calculations. One meter is equivalent to 100 centimeters. -The calculation of magnetic force involves the current, length of the wire, and the angle between the current and magnetic field. Increasing current or magnetic field strength results in a higher magnetic force. -The right-hand rule is used to determine the direction of the magnetic force acting on a current-carrying wire in a magnetic field. The force is perpendicular to both the current and the magnetic field. 16:07 Understanding the right-hand rule helps determine the direction of the magnetic force on a current-carrying wire. The magnitude of the magnetic force can be calculated using the formula F = ILB. -Using the right-hand rule to determine the direction of the magnetic force based on the orientation of the current and magnetic field. -Calculating the magnitude of the magnetic force on a wire using the formula F = ILB. 24:10 Understanding the right-hand rule is crucial for determining the direction of magnetic force. Magnetic force on a moving charge can be calculated using the equation F = Bqv sin(theta). -Right-hand rule helps determine the direction of magnetic force. Thumb points in the direction of current, fingers show magnetic field direction. -Equation F = Bqv sin(theta) calculates magnetic force on a moving charge. Current, charge, velocity, and angle are key factors in the equation. -Magnetic force direction depends on the orientation of charge and magnetic field. Use the right-hand rule to determine the force's direction. -For negatively charged particles, magnetic force direction is opposite to that of positively charged particles. Reverse the direction for negative charges. 32:15 A proton moving in a magnetic field perpendicular to its velocity will follow a circular path due to perpendicular forces. The radius of this path can be calculated using the equation r = mv / Bq. -Perpendicular forces cause a moving proton to follow a circular path in a magnetic field. The magnetic force acts as a centripetal force. -Electrons moving in a magnetic field experience a force opposite to protons, leading to circular motion in the opposite direction. The radius of the circular path can be calculated using the equation r = mv / Bq. 40:18 Calculating the radius of a proton's path involves using the speed, magnetic field strength, and charge. The energy of a proton in electron volts can be found by converting its kinetic energy. Wires with currents in the same direction attract each other due to magnetic forces. -Calculating the radius involves speed, magnetic field strength, and charge of a proton. The radius is found to be 2.09 centimeters. -Converting the proton's kinetic energy to electron volts gives 130,703 eV. The process involves understanding the relationship between joules and electron volts. -Electric potential is explained as energy per unit charge, with 1 volt equaling 1 joule per coulomb. The charge of an electron and its energy in electron volts are discussed. -Wires with currents in the same direction attract due to magnetic forces. The right hand rules are used to determine the direction of magnetic fields and forces between wires. 48:22 Understanding the force between parallel wires with current in the same direction, calculating the force magnitude, and applying Ampere's law for magnetic fields are essential concepts in electromagnetism. -Calculation of the force between two parallel wires with current in the same direction involves using the formula F = μ0 * I1 * I2 * L / 2π * R. -Ampere's law describes the relationship between current and magnetic fields, stating that the sum of magnetic fields around a closed path is equal to μ0 times the current enclosed by the path. -Solenoids, consisting of multiple wire loops, create strong magnetic fields at the center due to the cumulative effect of current loops, making them useful for generating powerful magnetic fields. 56:46 The strength of the magnetic field in a solenoid is directly proportional to the current passing through it and the number of turns per unit length, while inversely proportional to its length. -Increasing current or the number of turns per unit length in a solenoid enhances the strength of the magnetic field. -Decreasing the length of a solenoid also increases the strength of the magnetic field. 1:04:33 A current-carrying loop experiences torque in a magnetic field due to the force exerted on its sides. The torque formula is T = nIABsin(theta), where n is the number of loops, I is the current, A is the area, B is the magnetic field strength, and theta is the angle between the field and the normal line. -The torque on a current-carrying loop is due to the force exerted on its sides by the magnetic field. The force is perpendicular to both the current and the magnetic field, resulting in a torque that causes the loop to turn. -The torque formula for a single loop is T = nIABsin(theta), where n is the number of loops, I is the current, A is the area of the loop, B is the magnetic field strength, and theta is the angle between the field and the normal line. 1:12:56 Torque on a coil is greatest at 90 degrees between the magnetic field and the normal line of the coil, resulting in rotation. At 0 degrees, there is no torque due to parallel forces. -Explanation of torque at different angles. -Illustration of equilibrium at 0 degrees. 1:20:43 To find the maximum torque in a magnetic field, multiply the number of loops, current, area, and sine of 90 degrees. The magnetic field can be calculated by dividing the product of these values by the torque. -Calculation of maximum torque involves multiplying the number of loops, current, area, and sine of 90 degrees. -Solving for the magnetic field requires dividing the product of loops, current, area by the torque value

You explained it well and you handled the math in a clear and concise manner, but initially I didn't get the reference on "into the page" and "out of the page". You could maybe describe the field concept in a bit more detail. What is moving in and out? Electrons? (No, I get that. Gravitons(?), right.) But what is this 'field'? Is it just a "squiggle" in 3D space that will make a compass needle move once you get it close enough for the "squiggle" to over come the strength of the Earth's "squiggle". What is the squiggle made of? Is it doing work outside of our 3D space, ie does magnetism work function across collapsed dimensions or on 'out-of-phase' space(thought exercise). Questions like this keep me up at night.

I am a huge fan of your videos! Everything from Organic Chemistry to Physics has been so helpful! A friendly suggestion would be to add timestamps in your description to help your viewers follow along or skip to the part they are most confused about :)

One magnet cannot push or pull another magnet . Both magnets are are pulled toward or repelled from a spot in between the two that has either inertia or force in motion. The N° Doesn't connect to the S° . They are thr same and output force in motion (Repulsion) away from the pole. Each 'polar feild then runs through the center of the object toward the point of inertia (Attraction). Notice how the center is what pulls. The sides push. Any other way of thinking adds complexity that adds a severe learning curve due to flawed tutors descending from the literature of Einstein rather than Steinmetz.. Keep figuring out Magnetism. The universe has no magnitude without it.

I just learnt more in one hour than in an entire semester at college

[@klum8872]

It's my junior highschool year... Kinda intrested in these concepts.

[@coldblaze100]

good path

[@aryamaupadhyaya6014]

It's our senior high school and this is gonna be a part of exams so good going mann

[@ziwasewonani8052]

Thank you for saving my academic life😭

[@yueli2146]

I really like how you take time and build up the difficulty of the problems. Really boosts up my confidence as well as my understanding unlike college lecture which assumes you understand everything and just throws out abstract equations without explaining them.

[@williamsobidike218]

so true!!!

[@natnaelmesfin2193]

You have Our's great Respect ! BOSS 👏👏👏

[@williedavis1308]

Thank you hopefully this will help me on physic portion of the MCAT. I definitely feel more confident.

Isn't Biot Savart law included also in the video?

[@vivianneee98]

You have no idea how much you have helped me! So informative and amazing! :)

[@bedruomer8777]

Just a small mistake, it should be R ⬆️ -> B⬇️ 5:20

[@gooodgoood1313]

5:55 if you increase the strength of the magnetic field doesn't the radius decrease because there is an inverse relationship B=1/R

[@xXsharinganXx1]

good question, think about it this way; if you decrease the radius (or simply instead of going further away, get closer to the center) then the field is stronger there, this means that the strength of the field increases the closer you are to the center, decreases the further away you are, better?

[@gooodgoood1313]

Ohh Shit I get it now, good explanation thanks man, you should start your own channel

[@xXsharinganXx1]

no problem man, if you need anything else let me know and i would start a channel but im terribly awkward and i dont know anything about editing xD

[@gooodgoood1313]

I struggle with scalars and vectors, especially when to use Sin and Cos and Tan

You are a great teacher. I attended the Physics classes but I don't understand the lectures at all. Your video is precious for me and it helps a lot to prepare my final exam. Thank you.

I’d rather pay my tuition fees to this guy 🌚

[@battlewing221]

you can always donate.

[@yansirreaviles5036]

I’m studying for the MCAT and couldn’t remember these concepts at all. You helped me relearn material I haven’t seen in over 6 years. THANK YOUUU so so much!!

[@rhino2996]

Dude. I've been to physics classes watched videos from M.I.T. professors and this video trumps all those guys. Keep it up. Thank you.

ok its currently 11pm i have this exam at 7am whats my likelyhood of passing? i have a track record of not acheiving over 60 prior to these exams.
