WebRare-earth magnets are strong permanent magnets made from alloys of rare-earth elements.Developed in the 1970s and 1980s, rare-earth magnets are the strongest type of permanent magnets made, producing … WebThe two magnetic poles are in close vicinity, which concentrates the field lines and creates a strong magnetic field. Magnetic fields of a horseshoe magnet visualized using iron filings. A horseshoe magnet is either a permanent magnet or an electromagnet made in the shape of a horseshoe (in other words, in a U-shape).

WebThere are two different ways to make these magnets by sintering or pressing. The compound is calcined, wet ball milled to a fine particle size, binders are added, then the mix is compacted in a press. The compacted shapes are fired at high temperatures in kilns to a closely controlled temperature cycle. WebArtificial magnets are formed by wrapping a current-carrying conductor around the soft iron core. Artificial magnets are required because natural magnets have an odd and irregular shape and they are not magnetically very strong. Artificial magnets can be given desired shape and made very strong. Suggest Corrections 38 Similar questions Q. WebDefinition: Magnets which are made from iron in different shape and sizes for different uses are called artificial magnets. It is a magnetized piece of iron, steel, cobalt, or nickel. These magnets are of different sizes and shapes. They can readily be magnetized and demagnetized by turning the current on or off in the coil. css animace
