To make a magnet repel a metal, one must first understand the properties of a magnet. A magnet has two poles, a north pole and a south pole. When magnets are placed near each other, opposite poles attract and like poles repel one another. When a metal enters a magnetic field, all of...

I wanted to put between the magnets, metal pellets from in a thought that one of the poles will reject the pellets(north or south) But I've seen that both poles attracts the pellets. Is there a way to make magnetize reject the pellets so that they will be restless between two magnets...
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 to magnetize generally retain their magnetism for longer periods, while materials th...
By the 12th century, people had discovered that they could use lodestone to magnetize pieces of iron, creating a compass. Repeatedly rubbing lodestone along an iron needle in one direction magnetized the needle. It would then align itself in a north-south direction when suspended. Eventually, sci...

magnetize one by stroking one with a strong magnet repeatedly down its shaft, or by winding a coil of wire about it and powering it with a low voltage battery (electromagnet - please don't electrocute yourself by using mains current) or buy one. The previous answer to drill the head off...
The current running through the computer's circuitry magnetizes those tiny bits of metal. This is the same principle used in tape recorders, VCRs and other tape-based media (and yes, some of you still own tape decks and VCRs). This is why magnets can sometimes wreak havoc on the ...
Magnetize a piece of metal such as a paper clip, by rubbing it against a permanent magnet. The paper clip can pick up other paper clips and small metal objects. It will also behave like a small magnet. When it is attached to another object and brought near another magnet of similar stre...
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 ...
