Electromagnetism. A magnet is a material or object that produces a magnetic field. This magnetic field is invisible but is responsible for the most notable property of a magnet: a force that pulls on other ferromagnetic materials, such as iron, steel, nickel, cobalt, etc. and attracts or repels other magnets.
May 17, 2024 · 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.
Magnet is defined as a material that can produce its own magnetic field. There are three types of magnet: permanent magnet, temporary magnet, and electromagnet. Magnets are used in electric bells and generators.
an object, esp. a piece of iron, that is able to attract iron and steel objects toward itself: Magnets are used to attach the toy train’s cars to the engine. We use a refrigerator magnet (= small decorative magnet that will stick to a steel door) to hang our kids ’ latest drawings. fig.
May 16, 2024 · This motion can take many forms. It can be an electric current in a conductor or charged particles moving through space, or it can be the motion of an electron in an atomic orbital. Magnetism is also associated with elementary particles, such as the electron, that have a property called spin.
Jun 8, 2010 · Currently, physics has two explanations for why magnetic fields align in the same direction: a large-scale theory from classical physics, and a small-scale theory called quantum mechanics ...
Find out about everyday uses of magnets, how magnets attract and repel and their poles in this KS2 Science Explainer.
Magnetism is a subject that includes the properties of magnets, the effect of the magnetic force on moving charges and currents, and the creation of magnetic fields by currents. There are two types of magnetic poles, called the north magnetic pole and south magnetic pole.
In common language it is often understood that ‘magnet’ refers to a permanent magnet, like one that might adorn a family’s refrigerator, or function as the needle in a hiker’s compass. Such magnets are called ferromagnets.
Magnetic materials are always attracted towards a magnet. However, a magnet may be attracted to or repelled from another magnet.
