Consider a magnet surrounded by a wire with an on/off switch S as shown in figure. If the switch is thrown from the off position (open circuit) to the on position (closed circuit), will a current flow in the circuit ? Explain.

Text Solution

Verified by Experts


No, because when the switch S is closed there is no change in the magnetic flux linked with the coil, so no induced current will flow.
