Magnetic Field Surrounding Thin And Straight Semiconductor

The direction of magnetic field produced around a long straight conductor is given by

Magnetic Field Due To A Current Carrying Straight Conducting Wire

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.
