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.

Answer

N/a

Explanation

(i) The direction of magnetic field produced around a straight current-carrying conductor is determined by using Maxwell's right hand thumb rule.
(ii) The direction of force experienced by a current-carrying straight conductor placed in a magnetic field is determined by Fleming's left-hand rule.
(iii) The direction of current induced in a straight conductor moving in magnetic field is determined by Fleming's right-hand rule.
