A copper ring and a wooden ring of same dimension are placed so that there is same magnetic flux through each. Is induced current or induced EMF same in each case when flux · starts varying at the same rate in both.

Show that the rate of change of magnetic flux has the same units as induced e.m.f.

The magnitude of induced emf produced depends on the rate of change of magnetic flux through the coil. is this statement true.

A uniform copper ring is threaded by a steadily increasing magnetic field so that the magnetic flux through the ring is changing by a constant rate. Use a voltmeter to measure the voltage across the metal ring. What do you predict?

Production of induced emf in a coil due to the changes of current in the same coil is

Which of the four rings has the strongest magnetic field at its centre if same current flows through them ?
