Core Spring.

The first electric motor was invented in 1822 by Michael Faraday.The motor was developed only a year after Hans Christian rsted discovered that the flow of electric current creates a proportional magnetic field. Magnetic field: 1) A moving charge or current creates a magnetic field in the surrounding space (in addition to E). The resulting magnetic field looks very much like that of a bar magnet, as shown in Figure 20.15.

In classical electromagnetism, magnetic vector potential (often called A) is the vector quantity defined so that its curl is equal to the magnetic field: =.Together with the electric potential , the magnetic vector potential can be used to specify the electric field E as well. The core can be air or any material. the curl of the magnetic field is equal to the static electric current density, are invoked to compute the magnetic field and its related quantities due to electric currents and permanent magnets. magnetic fields.

Magnetic Field Due to a Thin Straight Wire. Because monopoles are not found to exist in nature, we also discuss alternate means to describe the

Mathematically, it can be represented as a vector field which can be plotted as different sets on a grid.

Electric current in a circular loop creates a magnetic field which is more concentrated in the center of the loop than outside the loop.

In Figure 2, a flyback diode was added in antiparallel with the solenoid.

In magnetics, to calculate the magnetic field of a highly symmetric configuration carrying a steady current, we use Amperes Circuital Law. Instead of spiking to -300 V, the flyback diode only allows approximately -1.4 V of potential to be built up (-1.4 V is a combination of the forward bias of the 1N4007 diode (1.1 V) and the foot of wiring separating the diode and the solenoid [dubious discuss]).

1. The number of turns N refers to the number of loops the solenoid has. In electrical engineering, the armature is the winding (or set of windings) of an electric machine which carries alternating current.

Because the magnetic field lines must form closed loops, the field lines close the loop outside the solenoid.

The rod on which the wire is wrapped is called a solenoid, and the resulting magnetic field radiates away from this point. But I didn't understand anything at all. The current to the coil windings is provided by a high current, very low voltage DC power supply, since in steady state the only voltage across the magnet is due to the resistance of the feeder wires.Any change to the current through the magnet must be done very slowly, first because electrically the magnet is a large inductor and an abrupt current change will result in a
