State properties of the material of the wire used for suspension of the coil in a moving coil galvanometer.

Explanation

The properties of the material of the wire used for suspension of the coil in a moving coil galvanometer are as follows:
1. It should have low torsional constant, i.e., restoring torque per unit twist should be small.
2. It should have high tensile strength.
3. It should be a non-magnetic substance.
4. It should have a low temperature coefficient of resistance.
5. It should be a good conductor of electricity.
