Look to see if it's got a coil connected to an electric power source or not. If it does, it's an electromagnet, if not, it's a permanent magnet.
One can purchase a permanent magnet motor online from Grainger where they have many available for around $400. One can also find them for purchase on ebay.
As far as can be ascertained from researching this question, there are no stores where one can buy magnet motors as they are not a proven technology. One can, of course buy magnets at many stores.
Permanent magnets can be found in stores that sell hardware or industrial supplies, as well as online retailers. Specialized magnet stores or suppliers may also carry a wide variety of permanent magnets for different uses.
A permanent magnet is a magnet which will keep its magnetism for a very long time and is difficult to change. No, As I think a permanent magnet means they have abilities to hold the magnetism when they are magnetized. Such as Alnico permanent magnets, but in fact, they can be demagnetized,such as high temperature, hit each other,pulse waves, out magnetic field influence...What's more, different permanent magnetic material, have different abilities on holding magnetism,they can be used in different environments. you can find some details from some manufacturers website, to learn some knowledges.
Someone that is looking to find information about induction motors can do so at the HappyWoodWorking website. There one can find a variety of information such as wiring a power switch, changing voltage or rotation and much more.
www.electricmotors.com has a lot of good information about electric motors. It also couldn't hurt to go to your local library and check out any books you can find on electric motors. There is also a lot of information that you can find online.
Although it can be difficult to find, it is possible to purchase a permanent magnet generator from auction sites such as eBay. Also, look at private persons through classifieds that build such devices and often sell them for a fair price.
Information on GM motors can be found on their own website. This gives loads of information about how and when they started and how they have developed over the twentieth and twenty first centuries.
Scrap cobalt can often be found in electric motors, particularly in permanent magnet motors that use cobalt-based alloys in their magnets. Additionally, cobalt can be present in some power tools and industrial machinery. To source scrap cobalt, consider dismantling old or broken electric motors and other equipment that may contain cobalt components, while ensuring proper safety and recycling practices are followed. Always check local regulations regarding the handling and disposal of electronic waste.
To make a magnet motor, you will need to create a rotor with magnets attached to it and a stator with coils of wire. When the rotor spins, the magnets induce a current in the coils, creating motion. You can find tutorials and kits online to help you build your own magnet motor.
