Wireless Charging Explained

If you assemble a second coil of wire and place it near the first, you can use the magnetic field from your electromagnet to create a flow of electrons in the second coil. If you hook that second coil of wire to a voltmeter, you can actually see the needle or readout change whenever you connect or disconnect the wires from the battery. Once you’ve got your nail wrapped in insulated wire, you can connect the two ends of the wire to the terminals on a battery. Electricity flows through the coiled wire, generating a magnetic field along the nail. If you switch the ends of the wire to the opposite terminals on the battery, you’ll reverse the polarity of your electromagnet — what was the north end of the magnet becomes the south end and vice versa. It’s easy to make a simple electromagnet — all you need is a battery, some insulated copper wire and an iron nail. Wrap the wire around the iron nail, leaving enough wire on either end to connect to the battery. Make sure each time you wrap around the nail that you’re going in the same direction.
