Need some help with Electromagnetism please :)

[redmosez]

Hey guys,

So I'm having some major problems with electromagnetism and it's driving me crazy!

I've got a couple of questions and any help will be greatly appreciated:

1) I've got a graph which is Induced Potential Difference Vs Velocity; how do I calculate the value of the magnetic field induction (B)

Do I just divide the gradient by length x number of turns?

2) What's the relationship between Velocity and Induced potential difference? are they proportionate?

Any help will be greatly appreciated

so therefore, induced emf is proportional to velocity.

and for part 1) if you know the length of the wire, you may use the formula above to calculate the magnetic field. (i am assuming its constant)

Thanks mate appreciate it
