The special advantages of horse−shoe magnet are:
(a) They produce a strong magnetic field.
(b) They produce a uniform magnetic field between their arms.
What are the special advantages of horse shoe magnets
A current carrying conductor is placed perpendicular to the magnetic field of horse shoe magnet the conductor is displaced upwards what will happen to the displacement of the conductor if (i) current in the conductor is increased (ii) a horse shoe magnet is replaced by another stronger horse shoe magnet and (iii) the length of the conductor is increased
