- HI, my name is Xave.Welcome to my house. I will show you an interesting thing inside.
- Hi, my name is Xave. Today I will show you about an interesting thing.
- Yup! My Room! This is my place to get inspiration for experiment.
- It’s about magnet. A magnet is a material or object that produces a magnetic field.
- Soft magnetic materials are magnetic materials with low coercivity and high permeability. They are easy to magnetize and demagnetize.
- Today I have idea to know about magnet. A magnet is a material or object that produces a magnetic field
- Magnets have certain important properties. They are attractive property, repulsive properties, directive property.
- The main difference between hard magnetic materials and soft magnetic materials is that hard magnetic materials have high anisotropy field, high coercivity, large hysteresis loop area, and large magnetic field required for technical magnetization to saturation.
- A simple way of mapping the rough shape of a magnetic field is to use iron filings. For example, the magnetic field pattern of a bar magnet can be detected by covering it with a piece of paper and scattering iron filings over the paper.
- A neutral point of magnet is a point at which a resultant magnetic field is zero.
- In general, the neutral point is obtained when a horizontal component of the earth’s field is balanced by the produced by the magnet.
