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, and
(iii) current induced in a coil due to its rotation in a magnetic field.

Explanation

The rules to determine the direction are :
(i) Maxwell.s right-hand thumb rule
(ii) Fleming.s left hand rule
(iii) Fleming.s right-hand rule
