Important Questions on Electromagnetic Induction and Alternating Currents



A metallic square loop is moving in its own plane with velocity in a uniform magnetic field perpendicular to its plane as shown in the figure. An electric field is induced

The figure shows three regions of magnetic field, each of area . In each region, the magnitude of magnetic field decreases at a constant rate . If is the induced electric field, then the value of the line integral, , along the given loop, is equal to

Figure shows three regions of magnetic field each of area and in each region magnitude of magnetic field decreases at a constant rate . If is induced electric field, then value of line integral along the given loop is equal to,


When magnetic flux passing through a coil is changed, the variation of induced current in the coil with time is as shown in graph. If the resistance of coil is , then the total change in flux through the coil will be,
