In the experiment to show that a current - carrying condcutor (rod) when placed in a unifrom magnetic field experience a force .What will happen if you experiences a force . What will happen if you interchange ther terminals of the battery connected in the circuit ?

Text Solution

Verified by Experts

The conductor (rod) will be deflected in the oppostie direction as the direction of the current is reversed .
