What is the energy dissipated as a function of time in a circular loop of n turns of wire having a radius of r0 and a resistance of r if the plane of the loop is perpendicular to a magnetic field given by b(t)=b0e−t/τ?

Explanation:

Let N be the number of turns in a circular loop having a radius of r₀ and a resistance R. The magnetic field is given by :

The induced emf in the circular coil is given by :

Where

Power dissipated is given by :

Energy dissipated in the circuit is given by :

Hence, this is the required solution.

force tends to be low and long diustance masses are high
