Neodymium, alloyed with iron and boron.
It depends on the composition of the metal plate. Magnetic materials like iron or cobalt would make the metal plate magnetic and attract a magnet. However, non-magnetic metals like titanium or stainless steel would not attract a magnet.
a scrap yard magnet is an electro magnet used to pick up bits of metal. this is used because it can drop the metal because it can be turned on and off
i don't think you can, but maybe if you had a all metal bey and a magnet and you used the magnet to control it. :) please spread word of meh idea
because magnet has a property that can attract metals/metal particles
Neodymium is the type of metal that makes the strongest magnet. It is commonly used in making powerful permanent magnets due to its high magnetism and strength.
Demagnetizing. Place the magnet at the opposite end of the metal from where you magnetized it. Again, the magnet must make as much contact with the metal as possible. Rub the metal with the magnet in the opposite direction that you used to magnetize it.
Magnets are usually metal, always metallic. A tool that cuts metal. A hacksaw for instance
Yes, a magnet can be used to separate small pieces of ferromagnetic metal from a mixture of metal. The magnet will attract the ferromagnetic metal pieces, allowing them to be easily separated from the rest of the mixture.
sometimes they have a magnet to catch metal shavings and particles
Sterling silver is a non-ferrous metal alloy, so a magnet will not stick to it. Many metals, however, are non-ferrous, so just because a magnet doesn't stick to a particular metal doesn't make it sterling silver.
Windings for motors.
