A 0.280 m radius, 475 turn coil is rotated one-fourth of a revolution in 4.17 ms, originally having its plane perpendicular to a
uniform magnetic field. (This is 60 rev/s.) Find the magnetic field strength needed to induce an average emf of 10,000 V.

To solve this problem we will apply the concepts related to the Magnetic Force, which is defined as the product between the currents multiplied by the length where they are transmitted and inversely proportional to the distance that separates them, considering between them, the costs indicated below . We will simply replace the values and obtain the desired value,
Here,
= Permeability of free space
= Current at each state
= Length
= Distance of separation
Replacing with our values we have that the force is,
Therefore the magnitude of the force is 3.63N, and if the currents are in same direction then force is attractive, while if the currents are in opposite direction then force is repulsive ( force is same).
