Repeat several times, stroking only in one direction, and only along half of the steel. Alternatively, you can magnetize a needle by rubbing it against your hair, some animal fur, or silk. Step 4 - Use a magnet and rub it along the needle in the same direction about 20 times. The Earth's molten metallic core means the planet is like a huge bar magnet, so when you charge a needle like this, it lines up with the magnetic field of the Earth and points north. Push the needle all the way through the disc so that about the same amount of needle shows on either side of the disc. Apply the fusible fleece to the wrong side of the fabric. However, iron nails can be magnetized. As we rotate the compass the earth's magnetic field interacts with the Place the north pole end of the bar magnet to one side of the screwdriver. The Earth's magnetic field alone is capable of weakly magnetizing the steel nail, without use of the loudspeaker magnet. When you take the compass away from the bar magnet, it again points north. For instance, you can use a HID card reader to open a magnetic lock, press the door buttons or push the handle. The needle of a compass is itself a magnet, and thus the north pole of the magnet always points north, except when it is near a strong magnet. At the geographic and magnetic south poles (which are 1,78 mi / 2,860 km apart), your compass would simply point toward magnetic north. 5.1 Apply the magnetic sticker. Complete! The flow of electricity can generate a magnetic field. Magnetism is one aspect of the combined phenomenon of electromagnetism.
