Question

Figure alongside shows insulated copper coil connected to centre zero galvanometer. The galvanometer shows deflection to the right when the north pole of a powerful magnet is moved to the right. Answer the following question:

The galvanometer shows deflection because:

Options

• Movement of magnet towards right changes magnetic flux in the coil.

• Due to change in magnetic flux, an induced e.m.f. is set in coil.

• Due to induced e.m.f, induced current flows in circuit.

• all of these.

Answer 1

All of these

Explanation:

When the magnet moves, the magnetic flux linked with the coil changes. This change induces an e.m.f. in the coil, and because the circuit is closed, an induced current flows. All three statements are correct, so the correct choice is all of these.
