Fleming's Left Hand Rule

Fleming's Left-Hand Rule

. To work out the direction of force experienced we use Fleming's Left Hand Rule. Your first finger points in the direction of the magnetic field (North to South). Your second finger points in the direction of conventional current (positive to negative    the Thumb represents the direction of Motion resulting from the force on the conductor The First finger represents the direction of the magnetic Field The Second finger represents the direction of the Current.

When a wire carrying an electric current is moved in a magnetic field of a magnet the magnetic field induced by the wire reacts with the magnetic field of the magnet causing the wire to move outwards. Fleming's left hand rule helps you to predict the movement

When electrons, or any charged particles  flow in the same direction (for example, as an electric current in an electrical conductor  such as a metal wire ) they generate a cylindrical magnetic field that wraps round the conductor 
the direction of the induced magnetic field is also sometimes remembered by the right-hand grip rule, as depicted in the illustration, with the thumb showing the direction of the conventional current, and the fingers showing the direction of the magnetic field. The existence of this magnetic field can be confirmed by placing magnetic compasses at various points round the periphery of an electrical conductor that is carrying a relatively large electric current.
magnet. The iron filings move and arrange into the lines. The magnetic field is the area around a magnet in which there is magnetic force. Moving electric charges can make magnetic fieldsMagnetic fields can usually be seen by magnetic flux lines. ... The flux lines can be seen by placing iron filings over
