What Is Magnetism? Definition, Examples, Facts

Magnetism arises from the electromagnetic force of a moving electric charge. A magnet has an invisible magnetic field surrounding it and two ends called poles. The north pole points toward Earth's... The north pole of a magnet is attracted to the south pole of any other magnet and repelled by the ...

How Electromagnets Work | HowStuffWorks

The rod on which the wire is wrapped is called a solenoid, and the resulting magnetic field radiates away from this point. The strength of the magnet is directly related to the number of times the wire coils around the rod. For a stronger magnetic field, the wire should be more tightly wrapped. OK, theres a little more to it than that.

What Is the Domain Theory of Magnetism? - Reference.com

The domain theory of magnetism explains what happens inside materials when magnetized. All large magnets are made up of smaller magnetic regions, or domains. The magnetic character of domains comes from the presence of even smaller units, called dipoles.

The process produces cyclically diminishing residual field levels and, if done properly, terminates at the origin, which is the point of zero magnetism. That is except for the Earth's magnetism, which cannot be removed by degaussing, its level ranging from zero to ½ gauss in the absence of nearby magnetic structures or deposits.

What creates Earth's magnetic field? - Cosmos Magazine

The magnetic field is extremely important to sustaining life on Earth. Without it, we would be exposed to high amounts of radiation from the Sun and our atmosphere would be free to leak into space.

Magnet | physics | Britannica

Magnet, any material capable of attracting iron and producing a magnetic field outside itself. By the end of the 19th century all the known elements and many compounds had been tested for magnetism, and all were found to have some magnetic property. The most common was the property of diamagnetism,

How to Demagnetize a Magnet - ThoughtCo

Demagnetization randomizes the orientation of magnetic dipoles. Demagnetization processes include heating past the Curie point, applying a strong magnetic field, applying alternating current, or hammering the metal. Demagnetization occurs naturally over time. The speed of the process depends on the material, the temperature, and other factors.

Magnet Manufacturing Process | How Are Magnets Made

Magnetic Stabilization & Calibration. In some instances magnets will require stabilization or calibration. Stabilization is a process of pre-treating the magnets, in or out of an assembly, so that subsequent use will not result in additional loss of flux output. Calibration is performed to narrow the performance output range of a group of magnets.

Magnetism for kids - A simple introduction

Electromagnets show that you can make magnetism using electricity. In fact, as European scientists discovered in the 19th century, electricity always makes magnetism when it moves about or changes. Every time an electric current flows in a wire, it generates a magnetic field all around it. Changing electricity, in short, produces magnetism.

Induced Magnetism & Electrical Method Of Magnetisation

Magnetic Induction is one of the ways making magnetic materials like steel and iron into magnets. In other words, magnetic induction is a process of inducing magnetism in an ordinary piece of magnetic material. This method involves simply placing the magnetic material (soft iron) close to a strong magnet without touching.
