Answer
(a) The force experienced by a straight conductor carrying current placed in a magnetic field depends upon the following factors:
1. It is directly proportional to the strength of the current.
2. It is directly proportional to the intensity of the magnetic field.
3. It is directly proportional to the length of the conductor within the pole pieces of the magnet.
(b) The direction of motion of the conductor can be found by Fleming's left hand Rule.
