If the coil is connected to a circuit and the switch is closed then, provided there is a power source, the coil will become energized.
Not much.
Detonate a high yield nuclear device in the upper atmosphere or just outside of the Earth's atmosphere. EMP was discovered at the US Nuclear Tests at Bikini Atoll when it knocked out power for a short time as far away as Hawaii.
The torque on the moving coil will reverse at twice the frequency of the supply, causing the pointer to vibrate. High-quality a.c. measuring instruments that incorporate a moving coil are, of course, common but incorporate a rectification circuit to supply the coil.
Thermal switch is to cut off the pilot ignition circuit when the heater temperature is beyond a set temperature. The thermal switch limits the temperature and protects the heaters
It (1) provides a means of connecting a rotating coil to the external circuit, and (2) it is a rotating switch which ensures that the direction of the current through the coil always acts in the same direction relative to the magnetic field in order to ensure its torque acts in the same direction.
If you switch the ends of the wire coil from one battery terminal to the other, the direction of the current flow through the coil will reverse. This will cause the magnetic field generated by the coil to also reverse its polarity.
check to see if the cam is turning. check coil by turning on and off the switch. have someone hold on to the big wire out of the coil.

Often a pickup coil is mounted inside a distributor to detect the position of magnets on a star wheel. The hall effect switch can be part of the pickup coil or a separate solid state device immediately adjacent.
In control circuit wiring the safety switch is in series with the holding coil.
I would say that nothing causes a coil to overheat except for a bad coil, replace the coil and see what happens.
When checking a resistive element coil for continuity, the selector switch on the multimeter should be set to the ohms (Ω) setting. This allows you to measure the resistance of the coil, confirming if there is continuity. If the meter shows a low resistance value, the coil is intact; a reading of infinity indicates a break in the coil.
The buzzer work with a magnetic coil that attractes the armature thus interrupting the current. This happens repeatedly to cause the buzz. When the current is interrupted the action of the coil produces a voltage that tries to maintain the current, and that causes a spark between the switch contacts.
Just put a switch in the power wire going to the coil.
Ignition what? Switch? Coil?
Nothing.
Sounds like the coil is bad on the one side ,need to replace coil .
