Thank you so much for all your magnetic field videos dude. Idk if you read comments but I really appreciate it all. I am revising for A-level physics (summer 2022) and your magnetic field videos explain things much better than my teacher did. I understand things a lot better now

Beautiful derivation and explanation. I would watch urs over khan's especially for Physics

[oscarcrofts]

brilliant explanation and derivation without this channel i would fail my a level

[ayeshashaikh]

you've no idea how thankful I am for these!

[miftahabdulkadir]

These videos have been so helpful since I had to learn from home

[prettyboypraise]

By far the best EMF definition I've seen. By far the best series of explanation. Way better than my teacher's explanation. I understand what they've been saying eay better now

[ameerasalama]

watching this 2 hours before my physics a level exam :)

[atomicbomber]

You my friend are going to get me a physics A level

[kyliek.]

3:00- faraday’s law
5:50- rate of change of flux=emf
15:00- faraday’s law

[aliabbas-xsqm]

I am not gonna lie, you explain thing way better then my physics teacher.

What an amazing video. Really helped me understand induced emf. Thank you very much sir. Love from Malaysia ❤

[unknownstar]

why is there an emf induced when a plane flies through a magnetic field but not when a loop is moving in a magetic field?

[waynebert]

I really like the connection to real life and the math correlation, food for the brain

[jackshanahan]

When you are using Change in B in the initial eqn (around 14:00) the change is negative, so it should surely be -0.2Ts^-1 not 0.2Ts^-1,


However this would make sense to cancel out when inputing the negative sign due to lenz's law.


Is that why you haven't included it or have I made a mistake?

[annalee]

Omg, i understand the Faraday‘ s law completely.

[kiransteward]

For the plane example at the end, surely the induced EMF will be 0 as when it's moving through the field the rate of change of flux density is 0.
Surely you are only interested in the area swept out when it is entering the field ?
Many thanks

It's about 12 days to my city and guilds exam and I've discovered this great channel. I'm sad

[timbale]

When you talk about a negative EMF, is that just an EMF flowing in the opposite direction?

[tomcaldwell]

Hi, Great video! You mentioned on the example of the coil that only when flux is changing an emf is produced, when the coil is fully in the magnetic field no emf is produced. But in the last example the plane is always fully inside the magnetic field, so how is an emf produced? Thanks

in the first diagram, if the 2 forces cancel out, how come you are able to find a change in mass from the scales if g is constant?
