Solution

The correct option is B
False

Heating (increasing temperature) has no effect on the strength of a magnetic field produced by current flowing in the coil. The strength of the magnetic field produced is the product of the current through the solenoid and the turn density (number of turns per unit length of the solenoid). Hence rise in temperature will not increase the magnetic field strength of a solenoid.
