On the Eastern sections of the Historic Columbia River Highway between Hood River and The Dalles the hillsides are now green in their sublime spring beauty. Wildflowers and wild grasses abound. Get out there in early spring, because the eastern Columbia River Gorge landscape is usually brown by the middle of May.
Magneto Motive Force is expressed as a current, I flowing through a coil of N turns. The magnetic field strength of an electromagnet is therefore determined by the ampere turns of the coil with the more turns of wire in the coil the greater will be the strength of the magnetic field.
The magnetic field of the primary coil collapses rapidly. The secondary coil is engulfed by a powerful and changing magnetic field. This field induces a current in the coils -- a very high-voltage current (up to 100,000 volts) because of the number of coils in the secondary winding. The secondary coil feeds this voltage to the distributor via a very well insulated, high-voltage wire. Finally, an ignition system needs a distributor.
