Whether it is a horseshoe-shaped educational magnet, a compass, iron powder, or a magnetic fluid magnetic calendar, these popular iconic teaching magnets have been widely used in classrooms and science laboratories to teach children physics for decades, experience the charm of education and science.
Educational magnets, they can help teachers, parents and students to explore mysterious forces of magnetism.
Normally educational magnets are made up of Alnico magnet and Ferrite magnet, which can be made into horseshoe shape, bar shape, etc. They generally have lower adhesion because they are only used to display the south and north poles. Some horseshoe magnets are small enough to fit in a pocket, but can still lift impressive weights.
A horseshoe magnet is a U-shaped metal object that produces a magnetic field. This magnetic field in invisible, but is responsible for a magnet’s notable pull on other metal objects. It is one type of permanent magnet, meaning that it stays magnetized, as opposed to an electromagnet, whose magnetic field can be started and stopped.
Originally, the horseshoe magnet was made as an alternative to the significantly weaker bar magnet. Its lifting strength is doubled, compared to that of a bar magnet, because both of its magnetic poles point in the same direction. For industrial applications, they have largely been replaced by even stronger magnets, but are still effective for uses such as classroom demonstrations and picking up small metal objects.
We usually paint educational magnet in the colors, red-green or red-blue, or we combine them with other materials such as metal and plastic. Meantime, these products comply with the international safety standards, and very safe to children’s health as well. Now we can also provide with N/S stickers, which is more environmental and nice.
Alnico horseshoe magnets provide a compact, high power magnetic source, and are used for traction, lifting, sorting, clamping and retrieval. They are supplied with ground pole faces, painted and with metal keepers for storage and to help retain magnetic strength. Maximum operating temperature is approximately 930°F (500°C). Alnico horseshoe magnets, also known as minor, pocket or power horseshoe magnets, are available in a number of finishes, dimensions & grades.
