Electric motors operate on the principles of electromagnetism, which describe how magnetic fields and electric currents interact to create motion. Some key principles of electric motors include:
-
Magnetic fieldsA magnetic field is a vector field that surrounds magnets and electric currents, representing the force exerted by either a magnet or a current-carrying wire.
-
ElectromagnetsElectric motors often use electromagnets, which are coils of wire that carry current, to generate magnetic fields.
-
Fleming’s left-hand ruleThis rule predicts the direction of force a conductor experiences in a magnetic field.
-
Magnetic field interactionWhen a current-carrying conductor is placed in a magnetic field, the magnetic field of the magnets interacts with the magnetic field produced by the electric current in the conductor. This causes the conductor to move, creating mechanical energy.
