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
Define Tesla and write its formula.
-
Ans 1: If a magnetic field exerts a force of 1N on 1m length of the conductor placed at right angles to the magnetic field carrying a current of 1A then the strength of magnetic field is said to be one tesla.1 T = 1 NA-1m-1

Question # 1
What is lamp and scale arrangement in galvanometer?
- Ans 1: In sensitive galvanometer,the angle of deflection is observed by means of a small mirror attached to the coil along with the lamp and scale.A beam of light directed towards the mirror of galvanometer.After reflection it produce a spot on the screen.The scale provides the small angle of deflection.
