A wire is kept horizontally at a place in the northern hemisphere of the earth . In what direction will force act on the wire due to the vertical component of the earth's magnetic field , if electric current flows through the wire from south to north ?

Text Solution

Verified by Experts

The correct Answer is:
2
When a wire is placed horizontally in the northern hemisphere and the current in it flows from south to north then according to Fleming 's left hand rule , the direction of the force acting on the wire will be along the west . The vertical component of earth's magnetic field is along `otimes` mark .
