Magnetism for kids - A simple introduction.

Magnets repel and attract other magnets, and attract magnetic substances. Magnetic fields can be shown using field lines. Magnetism is induced in some materials when placed in a magnetic field.

A magnet is a very special metal. When a magnet goes near a special kind of metal or other magnets, and the poles (sides) touching are opposite, it will pull, or attract the other metal or magnet closer. Also, if the two poles are the same, the two magnets will push away, or repel, from each other. See the fact file below for more information.

Demonstrate the force of magnetism to your classroom with our collection of children’s magnets. From the classic horseshoe magnet to colourful ring magnets, get your kids interested in physics and magnetism with a hands on and demonstrable approach!

Basic ring magnets without any additional machining can be magnetised with their north and south pole on opposite circular faces or diametrically magnetised so that the north pole is on one curved side and the south pole is on opposite curved side. They are used in many everyday appliances such as vacuum cleaners plus motors, generators, rotor shafts and more. You can also use ring magnets.

Magnets have been around for centuries. Lodestones were what the first magnets were called. Lode means lead; people used the stones to magnetize compass needles. The discovery of magnetite and the fact that it attracted iron was a cornerstone in the realization of the potential of magnets. The most famous legend of the discovery of the magnet.

Temperature effects on permanent magnets. When designing an application for permanent magnets it is essential to consider the temperature range that the magnet or magnets will be expected to work in. Yet, with so much information available (some of it incorrect) it is possible to associate the wrong magnetic property with the type of magnetic.

Magnets are important because of their properties. A particle moving in a magnetic field feels a force proportional to his speed, and to the field, so you can use a magnet that produce a field in a certain way and shape, in order to catch a partic.

Magnets are used in all kinds of applications, but do you ever wonder exactly why it sticks to certain metals? Find out the answer to this and other questions as we explore exactly how magnets work.

The three types of magnets are temporary, permanent, and electromagnets. Magnets are categorized by their source of magnetism. Temporary magnets become magnetized in the presence of a magnetic field. They lose their magnetism gradually, when the magnetic field is removed. Some irons and iron alloys, as well as paper clips and nails, function as.

In this lesson, you will learn what a magnet is and how it works at the atomic level. You'll also see how the earth's magnetic field works. A short quiz will follow.

Magnetism is the force exerted by magnets when they attract or repel each other. Magnetism is caused by the motion of electric charges. Every substance is made up of tiny units called atoms. Each atom has electrons, particles that carry electric charges. Spinning like tops, the electrons circle the nucleus, or core, of an atom.Their movement generates an electric current and causes each.
