Know how to make a magnet, at BYJU’S - The Learning App. Also know more about the magnet and how paper clip magnets, electromagnets and compass magnets are prepared.
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...

There are only a few elements in the periodic table that are attracted to magnets. None of the elements, by themselves, make good permanent magnets, but can become temporary magnets (when close to another magnet). When alloys of various metals are made, some of these alloys make very good...
On the other hand, the north end of one magnet will repel the north end of the other (and similarly, south will repel south). An electromagnet is the same way, except it is temporary — the magnetic field only exists when the electric current flows. You can determine the strength of a...

The most common method of making magnets today involves placing metal in a magnetic field. CRStocker/Shutterstock To make a permanent magnet, all you have to do is encourage the magnetic domains in a piece of metal to point in the same direction. That's what happens when you rub a needl...
To make a permanent magnet, all you have to do is encourage the magnetic domains in a piece of metal to point in the same direction. That's what happens when you rub a needle with a magnet — the exposure to the magnetic field encourages the domains to align. Other ways to align magn...
For enterprises aiming to make their mark in the international electronics sector,understanding the intricacies of international shippingis paramount. And since the journey of shipping electronics internationally involves meticulous planning, adherence to these specific protocols is a must to en...
The rotor here is like the nail in our previous example, and the stator is like the horseshoe magnet. When DC power is sent through the rotor, it creates a temporary electromagnetic field that interacts with the permanent magnetic field of the stator. The commutator's job is to keep the ...
