Magnetism (5 of 13) Magnetic Field of a Coil, An Explanation

[@miriamdouglas7645]

Thank you so much for these video . The equations examples/practice are incredibly help. It has taken a lot stress out of my study!

[@stepbystepscience]

Thanks for the comment, great that the videos are helpful to you.

[@TheParkourFamily]

This is honestly amazing. I love the approach you take where you talk about the math and then show some examples in the real world.

[@stepbystepscience]

Thank you very for saying so.

[@HeatherLukas-pv4hu]

Thank you for explaining the different equations that we could use. I am studying for my third electromag exam and i am making myself familiar with the formula sheet we are given for it. I was super confused until you showed us the 3 different equations we could use because we are only given the third one you presented on out formula sheet. I also appreciate how fast you talk. Engineering barely have time to do anything but study but watching your videos have given me a little free time haha.

[@stepbystepscience]

Glad it was helpful and gave you more free time!

Thank you very much sir. Love from Malaysia

[@My5t13]

concepts explained in a very understandable way. Thank you! Thank you! Thank you! Your videos would've been beneficial for my last exam but at least now I have your videos for my next exam. :-)

YOU ARE LITERALLY THE BEST

[@stepbystepscience]

Nice of you to say so...

[@zeyadramadan8759]

Thanks a lot for this lecture. Really great.

[@stepbystepscience]

Glad you liked it! Thanks for the comment.

The most priceless videos that I have seen in 20 years, but I still am left with my problem of 20 years,how to spin a bicycle rim in a steel frame using magnetism. John from. Oz

Brilliant , You are the best

[@stepbystepscience]

So nice of you, thanks!

[@chirots]

Thank you for your videos. Great explanation.

[@stepbystepscience]

You are welcome, glad you like them!

You are welcome, thanks for watching and commenting.

[@va5t680]

Brilliant.

[@stepbystepscience]

Thanks

[@va5t680]

@@stepbystepscience No problems, thanks for all the work you put in.

[@faithm6236]

Hi there, may I ask if there is a difference between the current of the wire and the current running through the coil?

[@julioequinones]

Thanks!

[@stepbystepscience]

Thanks for all the comments.

The Magnetic Field of a Coil is pretty interesting. Will you go over the magnetic field of the solenoids and how to calculate it? Also, explain how does that relative permeability of a coil affects the magnetic field of said coil and is it possible to calculate the torque of a coil?

[@ammaralhelal5603]

Hi, it is very useful video well done. i made a coil of 1/4" OD copper coil with a 17 turn and need to know what current and voltage required to get maximum magnetic field?

[@trinitiscruggs1563]

Would the length be the diameter of 1 loop or the length of all present coils?

[@stepbystepscience]

total length of the coil

[@crossdissolve7649]

Does the magnetic field flow from pole to pole? Like a current does?

[@stepbystepscience]

I would say that the magnetic field lines flow from the north pole to the south pole and electric field line go from the positive charge to the negative charge. Does that help?

[@crossdissolve7649]

Yes, that helps, thanks. Can you say what is flowing then?

[@zalida100]

In case you don't get a reply - The only thing that is flowing is current in the coil. When that field lines "flow," it just means that there is a magnetic force that has a potential to "push" something like iron filings (in the direction of the field lines) if you put them in the mag field. If there is nothing in the mag field then nothing will be moving. Unlike charge flowing in the copper wire for example. Is that any help?

[@red_juan]

Thank you so much for this helpful video, however I do have some questions regarding rectangular coils, say you have one rectangular coil, how will the magnetic field intensity formula become? And also sometimes I read science articles where they take B as constant, how do you explain that knowing for a fact that the current sometimes is not constant in certain circuits? Thanks again.

[@cynderrea461]

what must be the cause why magnetic fields at some points of a coil of wire collapses?

[@muhammadwahid2791]

when you say length, you mean the radius or diameter? or the length from the N to the S pole, please let me know

[@stepbystepscience]

I just mean the actual length of the coil.

[@wingedbull1257]

I have two N52 Magnets Size 2"L x 1"W x 3/8"H and Magnet wire Diameter 0.0367" 19Awg, I will have One Magnet face North and other South But I need to make One Magnet wire Coil that both Magnets will be rotating 360 degrees in center of One Coil to produce at least 14 Volt and light up 150 watts light bulb, Im at lost to know How many turns of magnet wire I need to do or have to produce what i'm looking for the out put.
