How do you make a microwave transformer electromagnet?
Microwave Transformer Electromagnet
- Step 1: Get a Microwave.
- Step 2: Take the Microwave Apart.
- Step 3: Discharge the Capacitor.
- Step 4: Remove the Transformer.
- Step 5: Gather the Required Hand Tools to Open the Transformer.
- Step 6: Locate and Cut Along the Weld Lines.
- Step 7: Pry Apart As Necessary.
Is there an electromagnet in a microwave?
The electromagnetic field of a microwave orients all of the positive ends in one direction. However the magnetic field reverses 4.9 billion times each second. This causes the molecules to flip back and forth attempting to remain balanced. This microscopic flipping motion creates friction-producing heat.
How are electromagnets made in a microwave oven?
The frames of three MOTs are cut open to remove the secondary coils and leave the cores exposed as poles for the future magnets. A shallow dish is fabricated out of steel and the magnets are welded in place.
How to get electromagnet out of microwave transformer?
Break off any visible insulation or glue holding the coil to the transformer. Drive the screwdriver or pry bar into the gap above the primary coil to slowly work it out. Repeat this on the left and right sides of the top and bottom. With the insulation and glue the wires will be very snug with the transformer core.
How to calculate the current of a microwave oven transformer?
If you know the Wattage of the transformer and the input voltage of the oven then you can calculate the approximate current the primary (thicker wire) can carry. Example: 500W 220V gives 500 / 220 = 2.273 Amps.
How can I protect my microwave from electromagnet?
Microwave ovens supply potentially lethal amounts of electrical power when operating. Protect yourself from electrocution by unplugging the unit before exposing the electronics. After it is unplugged, remove the microwave casing using a 6 point security screwdriver and a Phillips screwdriver. One of the security screw is shown in the image above.
