Question

Observe the diagram and answer the following questions a) If the end A of the solenoid is wound in anticlockwise direction, which pole will be generated at that end? b) After reversing the current through solenoid,if south pole of a bar magnet is brought near A , will it attract ? Explain

Answer 1

Answer:

clockwise the vibration is in the right side

Answer 2

Answer:

(a) The end of the solenoid at which current flows in the anticlockwise direction will act as a north pole and the end where current flows in clockwise direction will act as a south pole.

(b) The magnetic field produced in a current carrying solenoid is similar to that produced by a bar magnet.

(c) F=Bil=10
