1. A circular loop in the plane of the paper lies in a 0.40 T magnetic field pointing into the paper. The resistance of the coil is 2.55 Ω. If the loop's diameter changes from 23.5 cm to 4.00 cm in 0.55 s, what is the average induced current in milli-amps?
Ans in mA
A length of 20-gauge copper wire (of diameter 0.8118 mm) is formed into a circular loop with a radius of 15.0 cm. A magnetic field perpendicular to the plane of the loop increases from zero to 16.0 mT in 0.30 s. Find the average electrical power dissipated in the process.
