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.
Electromagnets are easy to make; just a few pieces of hardware and a power supply gets you on your way. First, you'll need the following items: one iron nail, at least 6 inches (15 centimeters) in length a length of 22-gauge insulated copper wire one D-cell battery Once you have...

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...
Meanwhile, a magnet possesses inherent magnetic properties and creates magnetic fields without the need for an external power source. The doorbell is a good example of how you can use electromagnets in applications where permanent magnets just wouldn't make any sense. When a guest pushes the ...
One method is to make a magnet out of a mixture of different types of metal. The metal is heated and melted, then placed in a cast, or container that's used
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...
This causes the magnetic domains to align and "lock" in place. When the external magnetic field is removed the domains will remain in their aligned positions and the material will be permanently magnetized. You can also make a magnet by passing an electric current through a wire coil. This ...
There is a simple vector magnetometer that you can make yourself. A bar magnet, hanging from a thread, will always point north; by marking one end of it, you can spot small variations as the magnetic field changes. By adding a mirror and light, you can take fairly accurate measurements ...
