1) A loop of wire with velocity 3 m/s moves through a magneticfield whose strength increases withdistance at a rate of 5T/m. If the loop has area 0.75m2 and internal resistance 5 Ω, what is thecurrent in the wire?
I=3 A
I=56A
I=11.25 A
I=2.25A
2) If you want to make a step-up transformer, youshould...
a) have more coils on the primary side than on the secondaryside.
b)have the same number of coils on both sides of thetransformer.
c) have more coils on the secondary side than on the primaryside.
d) give up, it's impossible to increase voltage with atransformer.
