Solution
The correct option is B
False
According to Oersted's experiment, the deflection in the compass needle takes place only when the switch is on. When you switch on the circuit, current starts flowing through the conductor. This produces a magnetic field around it, leading to a deflection in the compass needle when it is brought near to the conductor.
