1.	In activity 13.7 , how do you think the displacement of the rod AB is affected if [i] current in rod AB is increased, [ii] a stronger horseshoe magnet is used , and [iii] length of the rod AB is increased ?
Answer» Solution :i] When current in ROD AB is increased, FORCE on the conductorincreases. HENCE, thedisplacement of the rodincreases. ii] A STRONGER horseshoe magnet has a stronger magneticfieldand increases thedisplacementof the rod. iii] Since the force on the rod is proportionalto its LENGTH, thedisplacementincreases if the length of therod is increased.
