Please solve this electromagnet
Solution:
(iii) (a) The current in the conductor is from north to south. For force to act on it in the upward direction, the magnetic field should be from west to east i.e. from A to B. Hence, at A there should be north pole and at B there should be south pole.
(b) We have used Fleming's left hand rule to find the polarities.
