A thin cylinder of radius r, thickness s, and length L, is made of metal with a resistivity of ρ. The cylinder is resting in a uniform magnetic field B_{0}, with the field being in the same direction as the axis of the cylinder. The cylinder is then removed from the field. Find the current I_{0}that would be flowing initially, then find the rate at which energy would be dissipated by the resistance of the cylinder to the current flowing around it, and finally, find how long it would take at that rate for the magnetic energy in the cylinder to be dissipated.

2. Relevant equations

3. The attempt at a solution

I used B_{0}=(μ_{0}I_{0})/(2pi(r))

Then I solved for I_{0}=((B_{0})(2pi(r))/(μ_{0})

I'm not too sure of the equations that I need to solve parts 2 and 3 of the problem. Any help is greatly appreciated.
