How do you verify experimentally that the current carrying conductor experiences a force when it is kept in magnetic field?

Answer :

Method:

i. Take a wooden plank and make two holes in it.


ii. Fix the two wooden sticks into the holes.


iii. Pass the copper wire through the splits of the wooden sticks


iv. Connect the wire to a 4V battery and close the switch to pass the current through the wire


v. Bring the horse shoe magnet near the wire.



Observation: The force is experienced on the wire And on reversing the polarities of the magnet the direction of the force get reversed.


Result and Explanation: The Magnetic field of the horse shoe magnet overlaps with the magnetic field produce by a current carrying wire. Thus the non-uniform magnetic field is created around the wire( shown in the figure below). Therefore the wire tries to move to the weaker region of the magnetic field.
