What is a Permanent Magnet? (with pictures)

Dec 14, 2020· A permanent magnet is a magnet that is permanent, in contrast to an electromagnet, which only behaves like a magnet when an electric current is flowing through it.Permanent magnets are made out of substances like magnetite (Fe 3 O 4), the most magnetic naturally occurring mineral, or neodymium, a powerfully magnetic synthetic substance.The Earth itself is a huge permanent magnet

Magnet Wikipedia

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.. A permanent magnet is an object made from a material that is magnetized and creates its own persistent

Magnetite Wikipedia

Magnetite is a rock mineral and one of the main iron ores, with the chemical formula Fe 3 O 4.It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself. It is the most magnetic of all the naturally-occurring minerals on Earth. Naturally-magnetized pieces of magnetite, called lodestone, will attract small pieces
