A coil of wire wrapped around an iron core forms an inductor. In AC systems, an inductor's impedance appears equivalent to j*w*L (j = i = imaginary number, w = omega = frequency in radians, L = inductance).
A surge is inherently high frequency. Here's an example to help explain why this acts as a surge supressor:
Say I have a 10mH surge supressing inductor. My device uses 1 amp of current at 120 volts, so its' resistance is 120 ohms. Under normal operation (60 Hz), the inductor's impedance appears as (j*2*pi*60*10/1,000) 3.8 ohms. Voltage to my device is ~120 volts, and voltage dropped (or "supressed") is (3.8 / (120 + 3.8) * 120 ) = 3.7 volts. My device is only seeing 116.3 volts with this inductor in place, but that's not enough of a dip to hurt its' operation.
A power surge hits this device. This power surge is at a frequency of 50kHz, and a voltage of 80v (an overvoltage to my device of 120 + 80 = 200 volts). The impedance of the inductor "looks like" (j*pi*50,000*10/1,000) 3141 ohms, which is in series with my 120 ohm load. The surge voltage dropped across the inductor is (3141 / (3141+120) * 80) = 77 volts, so my device gets hit with ~3 surge volts (total voltage = 60 Hz voltage of 116.3 + 50kHz voltage of 3 = 119.3 volts).

If the primary coil has ten loops and the secondary coil has five loops then the secondary coil works as a 50% step down

A coil spring works by compressing and then expanding when a vehicle is going over pumps. Coil springs help make the ride a little smoother for most vehicles. The coils spring is attached to the undercarriage.
The meter movement has a current flowing through a coil. That coil is on a magnet. The electromagnet with the needle moves according to the current flow. That flow is established by resistive ladders inside the meter.
An electrical generator works by moving a coil of wire relative to a magnetic field.

You know that each 'wrap' or turn of wire in the coil has to go all the way around the coil-form, and you know how to calculate the distance around a circle. So all you have to do is count the number of times the wire goes around the coil, measure the coil's diameter, calculate its circumference, and multiply that by the number of turns in the coil.

The alternator or coil needs suppressing. Electrical devices make radio frequency interference. Go to an I.C.E shop for best suppressor.
One way you can write it is : She had to coil it around to activate it.Or you could say: I had to coil it for a project.
Is it possible you have a bad coil? It might need to be replaced. Is the wire from the coil to the distributor OK? Check and double check it to be sure. Has the electronic ignition fried? If you have power going in and no power coming out, I would guess, yes. A power surge will ruin these things. Check all the plug wires.
The condenser serves to enhance the spark by greatly increasing the voltage to the input of the ignition coil. It does this through a sudden electrical surge and a high frequency ringing effect, bringing the voltage as high as 300 volts for input to the coil immediately after the ignition points break.
