Permanent Magnet
Permanent Magnets are materials that can create a magnetic field even if the magnetization force is removed. Unlike other magnets, it keeps its magnetic power all the time. They are made of hard ferromagnetic materials, for example, Ferrite and Alnico.
Distinguished by their natural capacity to generate a magnetic field, permanent magnets effortlessly attract materials such as iron and steel. In this article, we will learn what is Permanent Magnets, their properties, applications, advantages, and disadvantages. We will also learn what how a Permanent Magnet differ from Non Permanent Magnet and Electromagnet.
