primary coil

Current passing through the primary coil creates a magnetic field.

The primary coil may be excited by any desired source of high frequency current.

The resistance of the pot, as viewed from the primary coil, appears larger.

A single primary coil can provide power to multiple secondary coils at the same time.

Changing the current in the primary coil changes the magnetic flux that is developed.

The magnetic field of the primary coil collapses rapidly.

To progressively feed energy/power into the primary coil with each cycle, different circuits can be used.

A capacitor is placed across the points which absorbs the energy stored in the primary coil.

In a maglev train the primary coil assembly lies below the reaction plate.

One coil of wire is called the primary coil.

The primary coil drew its current from a small generator, which in turn could be activated by the 2-peak hypercom signal.

The bogies are of welded steel construction with primary coil springs and secondary air suspension.

A linear induction motor consists of two parts: the primary coil assembly and the reaction plate.

The primary coil is connected to supply side while secondary coil supplies power to load.

Trigger of the primary coil.

The primary coil is first wound on the iron core, and insulated from the secondary with a thick paper or rubber coating.

The secondary coil normally has hundreds of times more turns of wire than the primary coil.

As the points open, point spacing is such that the voltage across the primary coil would arc across the points.

An alternating current in the primary coils accelerates electrons in the vacuum around a circular path.

Charge-time is the time mentioned above, the time during which the primary coil current is linearly increasing.

The second coils are then all tied together to form the neutral and the phases are connected to the primary coils.

This switch breaks the flow of current through the primary coil and causes a voltage spike (of perhaps 200 volts).

The magnetic fields in the primary coil assembly and reaction plate alternate, which generates force and direct linear motion.

The primary coil's current can be suddenly disrupted by the breaker points, or by a solid-state device in an electronic ignition.

As the field collapses there is a voltage induced (as described by Faraday's Law) across the primary coil.
