Fleming's Left-Hand Rule

Nota tambahan untuk Bab 3 : Elektrik (Teras) untuk Tingkatan 3..
subtopik Motor DC (direct current)..


You can figure out the direction in which the wire will jump using a handy mnemonic (memory aid) called Fleming's Left-Hand Rule (sometimes called the Motor Rule).

Hold out the thumb, first finger, and second finger of your left hand so all three are at right angles. If you point the seCond finger in the direction of the Current (which flows from the positive to the negative terminal of the battery), and the First finger in the direction of the Field (which flows from the North to the South pole of the magnet), your thuMb will show the direction in which the wire Moves.


That's...
First finger = Field
•SeCond finger = Current
•ThuMb = Motion
