(a) The direction of the induced magnetic field from a current carrying conductor is given by The Right-hand thumb rule.

Application: The direction of the magnetic field inside the solenoid is determined by Right-hand thumb rule.

(b) The direction of magnetic force acting on a current wire placed in a magnetic field is given by Flemings left hands rule.

Application: The direction of movement of the coil/loop inside an electric motor is determined by Fleming's left-hand rule.

(c) Fleming' right-hand rule is used to find out the direction of the induced current within a conductor when the conductor is moving in a magnetic field.

Application: The direction of induced current within a electric generator is determined by Fleming's right hand rule.
