1)An increase in the velocity of wire moving perpendicular through a magnetic field increases the induced EMF.

true. confused me

2)There are four coils of wire being used as electromagnets. They all have the same size and are made up of the same material but have a different number of loops. Which coil will produce a magnetic field with the maximum strength when the same amount of current passes through all coils?

A)a coil having 10 loops
B)a coil having 25 loops
C)a coil having 30 loops
D)a coil having 45 loops

I don't know how I would find this but I figured A.
