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)".
[4] [5] A popular example of a magnet motor, although without rotating axis, was put forward by John Wilkins in 1670: A ramp with a magnet at the top, which pulled a metal ball up the ramp. Near the magnet was a small hole that was supposed to allow the ball to drop under the ramp and return to the bottom, where a flap allowed it to return to ...
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]
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 effect of a time-varying electric field, which induces a magnetic field just as the motion of electrical charges does. display device Any device that displays data from an information system, such as a watch readout or an automatic scoreboard. dissipation The loss of energy in a system, such as dielectric loss in a capacitor. dissolved gas ...
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.
