Question # 1

What is B non zero outside a solenoid?

  • Ans 1: The magnetic field outside a solenoid is not zero.This is only true for infinitely long solenoid.Infinitely long solenoid can not be found in nature,The magnetic field outside a real solenoid is less dense that inside the solenoid and often one is only concerned with the field inside,which is approximately constant.

Question # 1

How can galvanometer be made more sensitive?

  • Ans 1: Since I=c/BAN theta
    A galvanometer can be made more sensitive if c/BAN is made small.
    Thus,to increase the sensitivity of galvanometer,c may be decreased or B,A and N may be increased.
