and the number of coils of wire. Its polarity depends on the direction of the current flow. While the current flows, the core behaves like a magnet, but as soon as the current stops, the magnetic properties are lost.Electric motors, televisions, maglev trains, telephones, computers, and ...
Here are a couple of neat things you can do with magnets to learn about how they work. But make sure you keep magnets away from computers and cell phones because they can damage them. What sticks to a magnet? Collect a bunch of small objects from around your house. Try to find objects...
magnets near computers is a Bad Idea®. There used to be rotating magnetic components in the drives and fans inside, plus they had wierd effects and could damage displays. Your approach sounds very clever, but rather than determining experimentally that it could cause damage, I suggest you ...
Magnets are an important part of our daily lives, serving as essential components in everything from electric motors, loudspeakers, computers, compact disc players, microwave ovens and the family car, to instrumentation, production equipment, and research. Their contribution is often overlooked because...
Therefore, keep them away from any magnetic based storage devices such as desktop or laptop computers, hard drives, floppy disks, cassette tapes, VHS tapes, or credit cards. They can also destroy computer monitors, VCR's and TV's, and other CRT displays. If you or someone in your family...
Ceramic magnets are brittle, making them susceptible to damage. If you drop a ceramic magnet on the ground, there’s a good chance it will break. Neodymium magnets, on the other hand, are physically harder, so they are less likely to break when dropped or otherwise exposed to stress. On...
Storage disk drives for laptops, desktops, tablet computers and smartphones. Fishing rod reels. Battery-less flashlights (shaking a rare-earth magnet flashlight creates energy to power the bulb). Roller coasters and other park rides. Motors for handheld power tools. Air conditioning servo motors....
Heat transport is effective in probing the magnetic excitations and magnetic phase transitions, and has been extensively studied for the spin-gapped systems. A large and ballistic spin thermal conductivity was observed in the two-leg Heisenberg S=1/2 ladder compounds. The characteristic of magnetic ...
especially large-size products, strips and thin slices, separate the magnet, please carefully shift staggered, must not break the hard pry, so as not to damage the product or injured , Separated to maintain a certain distance, so as not to touch the collision, damage to the product, or ev...
The permanent magnet materials are one of very important materials applied to electric and electronic goods and they are used in a very wide area--covering various types of home electric appliances, parts for automobiles and communication equipments and peripherals for large scale computers. Recently,...
