Pulser coil used for spark timing in automotive. industry.
12 Vdc
The coil spring provides suspension and absorbs shock.
If you are talking polarity. DC motors automotive application run poss to neg. But any dc motor can reverse by changing polarity.
The polarity of an electromagnet is determined by the direction of the electric current flowing through the wire coil. Reversing the direction of the current will change the polarity of the electromagnet.
in physics
DC shunt motor can be reversed by changing the polarity of either the armature coil or the field coil.

If you are looking to purchase coil packs, you can find them at Canadian Tire. Another place would be Part Source. Any automotive place will carry coil packs.
Yes. This testing procedure is valid for most automotive coils. Using an ohmmeter, check the resistance between the side terminals of the coil. Do this with all of the wires to the coil disconnected. You should see 0.75 to 0.81 ohm of resistance. Then check the resistance between either side terminal and the center high tension terminal. The reading should be 10,000 to 11,000 ohms. Any significant deviation from these numbers would indicate that the coil is defective.
Check your spelling - is the word you are requesting: polarity?
