This principle is used in an electromagnetic pump. The current is fed through a conducting liquid. Two permanent magnets are arranged to produce a magnetic field B ap as shown in the figure. The supplied current has a current density (J) and the magnetic field associated with this current can be called "Reaction magnetic Field (b rc)".
Magnetically coupled pumps, or magnetic drive pumps, vary from the traditional pumping style, as the motor is coupled to the pump by magnetic means rather than by a direct mechanical shaft. The pump works via a drive magnet, 'driving' the pump rotor, which is magnetically coupled to the primary shaft driven by the motor. [ 8 ]
The magnetic coupling has several advantages over a traditional stuffing box. [2] [3] Some aquariums use magnetic drive pumps, which have a magnetic coupling between the motor on the dry side of an aquarium wall and the propeller or impeller in the water on the other side of the wall. [4]
The same inductive pump technology can be applied to very small pumps delivering volumes in the micro-liter range to much larger pumps delivering volumes in the 10 gallon per minute range. Understanding of magnetic field propagation has led to increased design simplicity which is a hallmark of inductive pumps.
Electromagnetic propulsion (EMP) is the principle of accelerating an object by the utilization of a flowing electrical current and magnetic fields.The electrical current is used to either create an opposing magnetic field, or to charge a field, which can then be repelled.

Breakdown of ideal MHD (in the form of magnetic reconnection) is known to be the likely cause of solar flares. The magnetic field in a solar active region over a sunspot can store energy that is released suddenly as a burst of motion, X-rays, and radiation when the main current sheet collapses, reconnecting the field. [31] [32]
