The resulting magnet's strength depends on the amount of force used to move the domains. Its permanence, or retentivity, depends on how difficult it was to encourage the domains to align. Materials that are hard
A check of the spark plug to find a very dirty one. After cleaning the spark plug, the engine ran, but only for a few seconds. It lost a lot of fuel and stopped again. The fuel was... how to How to Magnetize a Screwdriver By Build.com Sep 12, 2011 Tools & Equipment ...
The impact can actually cause the atoms to fall out of alignment. You can magnetize them again by rubbing a magnet on it. Putting the 'Electro' in 'Electromagnet' Since you need an electrical current to operate an electromagnet, where does it come from? The quick answer is that anything...

Learning to visualize the flow of individual electrons was a breakthrough for me in understating tube amplifier electronics.Electric guitars generate an alternating current (AC) audio signal. The guitar's pickups are small electric generators. Pickups have magnets (poles) that magnetize the metal ...
(-) end of the battery. When the wire is connected to both ends, the current that flows through the wire magnetizes the nail. You can then use the nail to attract small metal objects, such as paperclips. Record which objects are attracted to the nail and which aren't, and which ...
During recording, the audio signal is sent through the coil of wire to create a magnetic field in the core. At the gap, magnetic flux forms a fringe pattern to bridge the gap (shown in red), and this flux is what magnetizes the oxide on the tape. During playback, the motion of ...
If your glasses are made of thin, stainless steel, break off an inch-long section, magnetize it by rubbing it in one direction against a wool shirt (or your hair), and set it to float on completely still water. The magnetized end will point north. ...
Ferromagnetic materials are elements that can easily magnetize and are usually made from steel, cobalt, nickel alloys, and soft iron. Ferromagnetic materials respond strongly to magnets. Subjecting these materials into a magnetic circuit will result in a more concentrated and denser magnetic flux which...
