Question

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.

State Fleming's right-hand rule. A conductor is moved vertically downward in a magnetic field directed from north to south (horizontally). Using Fleming's right-hand rule, determine the direction of the induced current in the conductor.
