Fleming's right hand rule

From Wikipedia, the free encyclopedia

Fleming's right hand rule (for generators) shows the direction of induced current flow when a conductor moves in a magnetic field.

The right hand is held with the thumb, first finger and second finger mutually at right angles, as shown in the diagram .

• The Thumb represents the direction of Motion of the conductor.

• The First finger represents the direction of the Field.

• The Second finger represents the direction of the induced or generated Current (in the classical direction, from positive to negative).

There is also a Fleming's left hand rule (for electric motors). The appropriately-handed rule can be recalled from the letter "g", which is in "right" and "generator".

These mnemonics are named after British engineer John Ambrose Fleming, who invented them.
