Question

A circular coil of 200 turns and radius 10cm is placed in a uniform magnetic field of 0.5T ; normal to the plane of the coil. If the current in the coil is 3A. Calculate 1) total torque on the coil.2) total force on the coil.3) average of force on each electron in the coil due to magnetic field.

Answer 1

The formula for time is: T (period) = 1 / f (frequency). λ = c / f = wave speed c (m/s) / frequency f (Hz). The unit hertz (Hz) was once called cps = cycles persecond
