1) A single circular loop piece of copper wire has a radius (r) of 12 cm. The magnetic field is parallel to the normal of the loop and it increases from 0 to 0.60 T in a timespan (t) of 0.45 s. The wire loop has a resistance per unit length of 3.3 x 10-2 ohm's/m.

What is the average electrical energy dissipated in the resistance of the wire?
