Flemings Left Hand Rule

Flemings Left Hand Rule
While passing electricity through a conductor placed in a magnetic field a force is experienced.
Hang a copper wire using very thin conducting wires. The ends of the thin conductors are connected to a battery via a switch. Place this arrangement inside the poles of a strong magnet and pass electricity through it. Now look, the conductor moves to one side. If we change the direction of flow of current, the conductor moves to opposite direction also.
A famous British scientist John Ambross Fleming put forward a rule to understand the directions of magnetic field, current and force exerted on the conductor.
Stretch the thumb, fore finger and middle finger of the left hand so that they are perpendicular to one another. The fore finger represents the direction of magnetic field, the middle finger represents the direction of the current and the thumb indicates the direction of the force. This is Flemings left hand rule.
