Question

A circular loop of wire with a radius of 12.0cm is lying flat on a tabletop. A magnetic field of 1.5T is directed vertically downward through the loop.

A. If the loop is removed from the field region in a time interval of 1.5ms , find the average emf that will be induced in the wire loop during the extraction process.

B. If the loop is viewed looking down on it from above, is the induced current in the loop clockwise or counterclockwise?

If the loop is viewed looking down on it from above, is the induced current in the loop clockwise or counterclockwise?

Explanation / Answer

A) induced emf = A*dB/dt

= pi*0.12^2*1.5/(1.5*10^-3)

= 45.24 volts

B) clockwise
