How is the magnetic field created in an ignition coil?
How is the magnetic field created in an ignition coil?
This winding lies inside the magnetic field created when electricity goes through the primary winding. When you switch on the ignition and the breaker points are closed, current flows through the primary winding, creating a magnetic field. When the points open, the flow of primary current stops and the magnetic field collapses.
What happens when you switch on the ignition coil?
When you switch on the ignition and the breaker points are closed, current flows through the primary winding, creating a magnetic field. When the points open, the flow of primary current stops and the magnetic field collapses. This sends current through the secondary winding.
How is an ignition coil inserted in a battery?
The coil is usually inserted into a metal can or plastic case with insulated terminals for the high voltage and low voltage connections. When the contact breaker closes, it allows current from the battery to flow through the primary winding of the ignition coil. The current does not flow instantly because of the inductance of the coil.
How much voltage does a secondary ignition coil have?
The high voltage on the secondary coil can be up to 40 kV depending on the ignition coil.

How does a 12 volt ignition coil work?
If your car uses a 12 volt battery, the 12 volts you put into the primary side of the coil will exit the secondary side as 30,000 volts! The high voltage is carried away from the coil by a high-tension cable that looks like a short piece of spark plug cable and runs to the distributor tower.
This winding lies inside the magnetic field created when electricity goes through the primary winding. When you switch on the ignition and the breaker points are closed, current flows through the primary winding, creating a magnetic field. When the points open, the flow of primary current stops and the magnetic field collapses.
What kind of wire is in an ignition coil?
An ignition coil is basically an electromagnet. It has an iron core with fairly thick wire (primary winding) wrapped around it a few hundred times. There is also a secondary winding – about 200 feet of thinner wire coiled between the iron core and primary winding.
Where is the primary winding on an ignition coil?
If your car uses a negative ground and you have a coil with primary and secondary terminals, the primary winding is connected to the terminal on the coil that is marked “+” or “Bat.” This is the terminal that receives voltage from the battery.
