LORENTZ FORCE! GO!

[@anikethdesai]

I just remember it as 'FBI' and coincidentally, it goes in correct order Thumb, Index Finger and Middle Finger respectively. Force (F) - Thumb, Magnetic Fields (B) - Index Finger, Current (I) - Middle Finger. Thank me later!

[@that1electrician]

No, its Merry Fkn Christmas. Motion, Flux, Current.

[@JoshHimler]

As an electrical engineer, I learned the right hand rule. I just had to look up the difference (and different uses) between left hand and right hand rules. Maybe that would have been useful to cover quickly or mention in your video?

[@jc-hq4sb]

I learned as the right hand rule didn't know is different for the left hand, bro if you could explain it it please would be great

[@No5elfCTRL]

Learned the right hand rule while learning electrical systems in the automotive industry

[@feecker]

Right hand rule is for positively charged particles meanwhile the left hand is used for negatively charged particles.

[@that1electrician]

@@feecker Ones for generators the other for motors. My teacher told us to remember General Motors gor left and right hand.

[@_Dreamer_9306]

In IGCSE Physics we took this: Left hand rule: Motors, protons and alpha particles. Right hand rule: Generators, transformers, electrons and beta particles.

[@B_Lane]

it all came together for me at the very end. thanks

[@devagarwal6966]

This helped so much! Thanks a lot!

[@bruce-le-smith]

Very cool, thanks!

[@moonjoe5164]

LEFT HAND RULE, JACK

NOW THERE'S A PRETTY MEME! EXQUISITE!

[@vairnenasyt5239]

STUDY THIS FOR YOUR FINALS, JACK!

[@Boringpenguin]

I still remember our first test on electromagnetism back in high school. Everyone was just rotating both hands like a maniac lol

[@muhammadmuneeb3792]

Thanks for this bro❤️ Now Iam finally able to use flemings left hand rule

[@ssamsvard]

youre a lifesaver man 🙏

[@electronic7979]

Helpful video. I liked it 👍

[@atinafalemu8966]

Wow best explanation ever

[@NepalXpeditions]

Very Helpful

[@DR_BLUE_CONTENT]

Thank you ❤

[@humayousuf9061]

Thanks it helped alot

[@andersemanuel]

F B I works for the LEFT -easy to remember! Thumb=Force, pointing finger=mag field, conventional current = flipping finger , Tada!

[@timewalkwalker]

Thank you so much for your explanations also for pdf 🗿

[@nickayivor8432]

My physics sir taught this too many times but I didn't understand a thing thanks so much :D

I was studying this topic coincidentally I got the notification of this video. Tomorrow is my physics exam ,Ready to rock the exam Hall🤘

[@Unique_vlogger_]

excellent

[@K-44BlackBumblebee]

MAGNETIC FORCE JACK, NATURE'S FORCE!

[@alster724]

THIS ONE'S ON ME!!!!

[@schmidt28117]

Going to Engineering school I learned a different right hand rule. It assisted in getting home from the pubs in the evening. Thumb to the nose. Middle finger to the horizon, first finger points to vertical. 8)

[@spideraraachnid9103]

Hey can you maybe make a playlist on Aerospace engineering

[@nswanberg]

I like to use open palm direction for force or movement.

[@richtigmann1]

this one video just made all the electromotors make sense

[@ayush-that]

nice

[@undividedself1]

How do we apply Fleming's LHR to a *proton* moving at right angles to a magnetic field?

[@hidad5601]

If you live in Australia we swap the left hand with the right, vise versa becasue we are upside down.

[@MDMAx]

The way I remember this rule: federal bureau of investigation = FBI = Force, Magnetic field, Current; from the thumb downwards

[@warrenscorner]

Awesome animation! I’ve searched your videos looking for something about RF welding. There are many RF welders where I work. They manufacture single use medical products such as IV bags. I’ve been curious how these machines actually work. I’ve been told it’s similar to radar or a microwave but it’s black magic to me. Even on a rare occasion that we had to call in a technician to repair one of these machines they can’t really explain the process. That leaves me thinking that they really don’t know either. In my opinion if you can’t explain it you don’t know it. Have you ever considered doing a video about this process?

[@Leo-lg9tu]

Fleming's left hand rule-THumb~ THrust or force. First finger~ Field finger. SeCond finger~Current.

[@christosvoskresye]

Or, you could just use F/l = I x B -- the Lorentz Force on a wire -- and use the Right Hand Rule as with all other cross products.

[@Dany2k13]

More importantly what's the difference with the right hand rule? Because that's the convention used in my textbooks... These conventions gave me a lot of headaches for nothing... Now I just use the right hand rule for everything. Just have to keep in mind the difference between generators and motors !

[@sjefoekel6058]

There is also the corkpuller rule

[@granitfog]

Or you could use the T_Rat RIGHT hand rule… THE index finger also known as the pointer finer points in the direction of current flow ( pointer finger points in the diection of what you know first which is the current diection- easy to remember), THE middle finger points in the direction of the magnetic field N_S (middle - magnet, easy to remember) THE Thumb (first digit) is the direction of force (first - force, easy to remember) By the way, I have NEVER seen any one refer to the index or pointer finger as the finger number one, except on this video.

[@Omar-ww6dp]

MFC M motion F field C current

[@dhgodzilla1]

The real Question here is, does this Hand Position measure up to the Shocker?

[@benlee3545]

Hi I am a bit confused because current flow from negative to positive. So in actual fact will the force be always in opposite of this theory or rule?

[@hazelorchards2118]

This topic uses conventional flow and not electron flow, so current flows from the positive to the negative.

[@dunnkruger8825]

Interesting But I don’t get how to use

[@dwayne7356]

As a non-electrician but an operator who has had sync very large generators to the grid, I still can't put this into practice. Maybe I just need to connect up a few motors and I'll finally be able to apply this rule. And for the life of me, I can't find out how you can carefully disconnect a 3-phase motor and an exact replacement and installed as marked when removed, runs backwards. I understand the rule, I just can't put into practice.

[@EngineeringMindset]

We have a video where we show how to design and build a motor. Then you use left hand rule to work out the rotation to see it. Give that a go

[@RODOLFO.M.S]

[@Oladavol]

I do not fully understand what is meant by the downward and upward force for the wire. What lower tier education am I missing to understand this?

[@deviii9723]

no one. absolutely no one. me during my physics exam: ☝👇👆👉🤟👆

[@TheBenlueks]

im gonna pass my ip!! study so much

[@jovancabs]

Ok

[@captainwin6333]

Fleming was a gangsta.

[@mattfleming86]

As a left handed Fleming, I assert that this was the greatest discovery of all time. Okay.. maybe second to Relativity.. but a close second.

[@ak-47821]

why can't we just use right hand rule and use electron flow instead of conventional current?

[@NavajoNinja]

...and 'the stranger' is when u sit on ur left hand till numb, then...

[@suunraze]

It's easy to update this for modern usage/terminology: Index finger is force (intuitive) Thumb is magnetic field Three small fingers are electron flow (they make the shape of an E) Also works for EM waves: Index finger is wave propagation Thumb is magnetic field Three fingers are electric field This is way more intuitive and simple than trying to use Fleming's original rule and then flip the result 180°
