    Apr 24,  · Magnetic materials should maintain a balance between temperature and magnetic domains (the atoms' inclination to spin in a certain direction). When exposed to extreme temperatures, however, this balance is destabilized; magnetic properties are then affected. While cold strengthens magnets, heat can result in the.

    Magnets are a direct result of the physics taking place at the atomic level (i.e. quantum level) within the material of the magnet. Magnetic fields are polarized with two magnetic poles called North and South. One of the interesting features of a magnet is that, if you break it into smaller pieces, it will still have magnetic north and south poles.

    Unless the iron is a very thin needle, the magnetism breaks up into domains pointing different directions, so that they don't repel their neighbors. There's an art to making permanent magnets, finding materials in which the domains are strongly magnetized yet have trouble flipping around. Mike W. (published on 02/16/).

    In other words, the current in the coil imitates a magnet. It appears, then, that a piece of iron acts as though it contains a perpetual circulating current. We can, in fact, understand magnets in terms of permanent currents in the atoms of the iron. The force on the magnet in .

    2. Medical magnets - Magnetic resonance imaging, or MRI, is a process that allows doctors to "see" inside an individual to determine a diagnosis, decide if surgery is necessary, and more. Unlike an X-ray that shows almost exclusively the skeletal system, MRI allows doctors to see muscles, tendons, ligaments, and more with some degree of clarity. 3.

    Magnetism 9 Name Date Class Earth’s Magnetism Earth is surrounded by a magnetic field that is similar to the magnetic field around a bar magnet. Magnets have a north magnetic pole and a south magnetic pole. Earth’s south magnetic pole is near the north geographic pole, and its north magnetic pole is near the south geographic pole.

    But with magnetism, you always have a dipole. if I were to take this magnet, this one right here, and if I were to cut it in half, if I were to cut it in half, somehow, miraculously, each of those halves of that magnet will turn into two more magnets, where this will be the south, this will be the north, this will be the south, and this will be.
