An emf of 25.0 m V is induced in a 500-turn coil when the current is changing is at the rate of 10.0A/s. What is the magnetic flux through each turn of the coil at an instant when the current is 4.0 A?

if the above magnetic field is present perpendicular to a ring of radius of 1 cm mass = 10 g and charge =1 C then the angular velocity of the ring as a function of time is
