I don't have a bar magnet or multimeter. But I have magnetic wire and a voltmeter. I also bought a flashlight from the 99 cent store that I can crank to charge. When I took it apart, I found a coil and weak round magnet. It charges with DC since the magnet only moves in one direction and the...
I know 140 watts is a lot. That is why I did not connect the inverter to a car battery or house socket. I also didn't think that 10 1.2 volt AA batteries could produce 140 watts. The inverter also has a fuse, so I thought it would blow before it hurt anyone (it did not). So I assumed that the...
I lay the inductors on a desk and place the tips close together. I then used the inverters for cars that allows you to plug a house socket into your car. I connected 12 volts worth of AA batteries to it. It is a 140 watt inverter and I connected it to an inductor. Then I placed the tip of that...
Hello,
I was wondering how I can induce a current to power an led? I tried using two 100 uH inductors but they did not work. I was using an AC current from a car inverter.
Thank you.
