Working principle of magnetic pump
Thread Content
How does the external magnetic rigid rotor of a magnetic pump use magnetism to drive the internal magnetic rigid rotor?
By utilizing the principle that like poles of N-S magnets repel each other while opposite poles attract, the motor drives the external magnet; this external magnet, together with the permanent magnets on the internal magnet, creates a magnetic circuit that facilitates the rotation of the internal magnet
Called a magnet or magnetic steel, not magnetic rigid :)
