If the ratio of secondary to primary turns in an ideal transformer is 4:5, what will be the ratio of power output to power input?

A magnetic material has a total flux B of 80 micro Wb with an MMF of 160 AT. The reluctance in ampere turn per weber is _____.

When a magnetic needle is placed in a non-uniform magnetic field, it experiences:

A particle of charge q and mass m moves in a circular orbit of radius r with angular speed ω. The ratio of the magnitude of its magnetic moment to that of its angular momentum depends on

Whenever the magnetic flux changes with respect to an electric conductor or a coil, an EMF is induced in the conductor. This is known as Faraday's

In the case of DC shunt motors, the speed is dependent on back e.m.f. only because

According to Coulomb's law, the force of attraction or repulsion between two electrical charges is
