Permanent Magnet
When a material is magnetized, it acquires magnetic properties that allow it to attract or repel other magnetic materials. However, not all magnetized materials retain their magnetic properties. Permanent magnets, on the other hand, are those types of magnets that maintain their magnetic properties even after the magnetizing force is removed. They are commonly used in a wide range of applications, including electric motors, generators, and magnetic storage devices.
Here are some methods to demagnetize permanent magnets:
- Subjecting the magnets to extreme temperatures.
- Hammering the magnets can loosen the magnetic attraction between their atoms.
- Rubbing one magnet against another can weaken its magnetic strength.
- There are four types of permanent magnets.
- Ceramic or ferrite
- Alnico
- Samarium Cobalt (SmCo)
- Neodymium Iron Boron (NIB)
What is a Magnet?
Magnet is a physical object that can generate a magnetic field around itself, and this field is called Magnetic Field. This magnetic field is responsible for attracting unlike poles and repelling like poles. In other words, a magnet has the power to draw in magnetic materials toward itself and push away those materials that possess similar magnetic properties. The study of magnets is important for Class 6, Class 8, Class 10, and Class 12.
In this article, we are going to learn about what is a magnet, the properties of magnets, the poles of magnets, the magnetic field of magnets, types of magnets, and the applications of magnets.
