What is meant by the tern,”Magnetic field”? Why does a compass needle shows deflection when brought near a bar magnet? ( CBSE 2008)

Magnetic field – The region around a magnet in which force of the magnet can be experienced. A compass needle is a small bar magnet so it experience the force of the bar magnet when brought near it and deflects.

State the rule to determine the direction of a:

(i) magnetic field produced around a straight conductor carrying current.


(ii) force experienced by a current-carrying straight conductor placed in a magnetic field which is perpendicular to it.


(iii) current induced in a straight conductor moving in a magnetic field. ( CBSE 2005)
