Question

In suspended type of moving coil galvanometer

• A. coil is stationary.
• B. magnet is stationary.
• C. magnet and coil are stationary.
• D. magnet and coil are moving.

Hint:

In all moving coil galvanometers, the deflection is due to motion of the coil, not the magnet.

Answer 1

The Correct Option is B

Step 1: Structure of suspended type galvanometer.
In a suspended type moving coil galvanometer, the coil is suspended by a thin fibre and is free to rotate when current flows through it.

Step 2: Role of magnet.
The permanent magnet provides a strong radial magnetic field and remains fixed in position.

Step 3: Deflection mechanism.
When current passes through the suspended coil, it experiences a torque and rotates, producing deflection. The magnet itself does not move.

Step 4: Conclusion.
Thus, in a suspended type moving coil galvanometer, the magnet is stationary.
