How to Make Super Strong Permanent Magnets Sciencing
Mar 09, 2018All the possible ways to make a permanent magnet are listed in Joseph Henry's student notebook, which is kept at Princeton University. Henry, the 18th century American physicist, is known together with Michael Faraday as the father of electrical technology, so it's no surprise that one of the methods he describes uses electricity.

Neodymium magnet Wikipedia
A neodymium magnet (also known as NdFeB, NIB or Neo magnet) is the most widely used type of rare-earth magnet.It is a permanent magnet made from an alloy of neodymium, iron, and boron to form the Nd 2 Fe 14 B tetragonal crystalline structure. Developed independently in 1984 by General Motors and Sumitomo Special Metals, neodymium magnets are the strongest type of permanent magnet

Is a Permanent Magnet Motor Feasible? Power Electronics
Is a Permanent Magnet Motor Feasible? We recently published an article on the Power Electronics with the headline, “Unique Motor Uses Only Permanent Magnets No Electric Power Required.”We received a firestorm of criticism that this sounded like a perpetual motion machine and that it defies the law of conservation of energy and the law of thermodynamics.

Permanent Magnets and Their Applications
Magnets are used in many different applications given their inherent strength in relation to mass and weight. Electromagnets, because they can be turned off and on, are used in powerful pieces of equipment and vehicles, such as magnetic-levitation, or maglev, trains.However, permanent magnets are also very versatile and strong components of myriad applications as well.

What is a Permanent Magnet? (with pictures)
Aug 18, 2020A 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.
get priceMagnet 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, and attracts or repels other magnets.. A permanent magnet is an object made from a material that is magnetized and creates its own persistent magnetic

Permanent Magnets vs Electromagnets Adams Magnetic
If a permanent magnet loses its magnetic properties, as it does by heating to a (maximum) temperature, it will be rendered useless and its magnetic properties can be only recovered by re-magnetizing. Contrarily, an electromagnet loses its magnetic power every time an electric current is removed and becomes magnetic once again when the electric
