Question

what happens to the deflection of the compass needle placed at a point near current carrying straight conductor:

I) if the. current is increased
2) if the direction of current in the conductor is changed?
3) if the compass is moved away from the conductor?​

Answer 1

Answer:

if current in the wire is increase then the needle of the compass needle place at that get deflected by a large angle. the straight of magnetic field at a point due to this current carrying conductor is directly proportional to the current....
