Calculating Energy Dissipated in Copper Wire Loop Due to Magnetic Field Increase

[StudentofPhysics]

A piece of copper wire is formed into a single circular loop of radius 9 cm. A magnetic field is oriented parallel to the normal to the loop, and it increases from 0 to 0.45 T in a time of 0.45 s. The wire has a resistance per unit length of 3.3 10-2 /m. What is the average electrical energy dissipated in the resistance of the wire.


I know the emf = 0.254 Volts.

How do I find the energy dissipated?

Start by finding the current that flows through the wire.
