How Permanent Magnet Generators Work? - DC Generators, PM ...

Permanent magnet generators are superior alternatives to traditional induction motors that can be coupled with turbines, diesel generators and used for hybrid vehicles. One of the biggest benefits of permanent magnet generators is that these do not require definite environmental conditions to work properly which allows them to be used for wind energy and water [.]

What is a Permanent Magnet? (with pictures) - wisegeek

Aug 18, 2019 · 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 .

Permanent Magnet DC Motor (PMDC Motor) – How Do They Work?
Permanent magnet DC (PMDC) motors | electricaleasy

A permanent magnet DC motor also works on the same principle. Construction. In a PMDC motor, permanent magnets (located in stator) provide magnetic field, instead of stator winding. The stator is usually made from steel in cylindrical form. Permanent magnets are usually made from rare earth materials or neodymium.

How Magnets Work | HowStuffWorks

The magnetic field's lines of force exit the magnet from its north pole and enter its south pole. Permanent or hard magnets create their own magnetic field all the time. Temporary or soft magnets produce magnetic fields while in the presence of a magnetic field and for a short while after exiting the field.

How a Permanent Magnet Works - IMS Magnet Trading

How a permanent magnet works. To explain the workings of a permanent magnet we need to look inside, on an atomic scale. Each atom has a set of spinning electrons, which together act to form a magnetic moment. For our purposes, we can consider each atom to act like a small bar magnet.

Permanent magnet synchronous generator - Wikipedia

A permanent magnet synchronous generator is a generator where the excitation field is provided by a permanent magnet instead of a coil. The term synchronous refers here to the fact that the rotor and magnetic field rotate with the same speed, because the magnetic field is generated through a shaft mounted permanent magnet mechanism and current is induced into the stationary armature.

Magnets with an OFF Switch - K&J Magnetics

It's also opposite of a "temporary" magnet, like when you stick a (permanent) magnet to a steel paperclip, and that steel acts like a magnet as long as the (permanent) magnet is stuck to it. Remove the magnet, and the paperclip stops acting so magnet-like. When people ask us for magnets that can be turned off, we say it's not possible.
