Guide the wire through the notch on the insulating washer, scrape the insulation off and solder it to a lug at the terminal marked ‘2’. The cores of the electromagnet are made of soft bar steel one inch in diameter and three inches long. Many many years ago I worked at a shop that built these as well as just about magnetic device you coud want. Testing the charger Once the unit is wired according to the wiring diagram, it’s time to test it. There was a problem filtering reviews right now.Īn identical washer without terminals is epoxied to the other end of each pole piece. In other words, the charged magnet comes off the charger with its south pole originating from the north pole of the charger. Build a Magneto Magnetizer / ImperfectĪpplying three layers builf No. The coils are connected in parallel nuild protected with diode arc suppressors. In case you are wondering, a magneto is a small, mechanical generator of electric sparks that works by exploiting the principles of electromagnetism. The metal core however is of very heavy steel and some machining operations may be required. Dave will show you how a magneto works, how to test one, how the magnetizer works and will show you in detail how to build one. Build a Magneto Magnetizer, Gingery, David J, ISBN Build a Magneto Magnetizer Many people collect and restore old engines and in the process discover that the old iron magnets in the magneto.
