Magnetizing metal involves lining up the positively and negatively charged particles within the metal to create a stronger attraction with oppositely charged metal objects. You use a magnet to do this. Opposite ends of a magnet have densely packed, and oppositely charged, particles that attract parti...
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...
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...
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 ...
I don't think you quite understand what I am going to do, I'm going to use a solenoid made from wires from an extension cord. I'm not going to use the Earth's North and South poles to magnetize my circular magnet, but instead, a very powerful solenoid wrapped around it. Jun 16,...
In a typical reed switch, the two contacts (which look like metal reeds) are made from a ferromagnetic material (that means something as easy to magnetize as iron), plated with a hardwearing metal such as rhodium or ruthenium (to give them a long life as they switch on and off), and...
is there a way to reverse magnet to magnetize non-metals instead of metals? 2 Moses Damulira ⚠ Thanks for such educative information,My questions are: How can permanent magnetization be removed?,What role does a magnet play in a loud speaker so that we can hear and how does the mechani...
Tip: Magnetize the end of your Allen wrench by passing it through a magnetizer/demagnetizer, a small plastic gadget with a high strength magnet embedded in it. Pass the end of the hex wrench through it and the magnetic charge it imparts allows the tool to hold onto the screw after it ha...
Pickups are designed to magnetize the vibrations of your guitar strings or "pick them up" and transfer them as an electrical signal. If the strings above your pickups are old or worn out (or both), the quality and clarity of those vibrations are going to suffer as well. One of the simp...
