Question

The situations below show eight rectangular wire loops that ore moving UP into, within or out of a region in which there is a uniform magnetic field coming out of the page. The rectangular loops are the same size (0.05 m Times 0.10 m) and are being pushed up at a constant velocity (0.02 m/s). The loops are at various locations with various portions (25%. 50%. 75%. 100%) within the field and oriontations in the field below. Rank the situations from greatest to least, on the basis of the magnitude of the current in the rectangular loops at the time and positions shown (assume there is no effect or interaction between the loops). Explain your answer

Explanation / Answer

Force acting on the loop,F=I(L XB)

I=current produced

B=MAgnetic field applied

L=length of the loop

So the current,I=F/(L X B)

So when L inceases current decreases

When B increases Current decreases

More current is thus for:

A > F > B > C> H > G > D =E
