Isotropic Magnet and Anisotropic Magnet
There are two kinds of magnet, isotropic and anisotropic.
■Isotropic＝Magnet with same strength can be made by magnetizing from any direction of a cube.
■Anisotropic＝By magnetizing from a specific direction, a directional magnet can be made.
■Isotropic＝Magnet with same strength can be made by magnetizing from any direction of a cube.
■Anisotropic＝By magnetizing from a specific direction, a directional magnet can be made.
Why are the magnetic characteristics different?
E.g.:Ferrite Crystal and Easy Magnetization Direction
The shape of a ferrite crystal is similar to a short hexagonal prism. By magnetizing in the direction of the prism height, a strong magnet can be made.
Crystal Arrangement of an Isotropic Magnet
As the crystal direction and arrangement of isotropic crystals are various, so a magnet with the same strength can be made by magnetizing from any arrow direction.
Crystal Arrangement of an Anisotropic Magnet
As the crystal directionand arrangement of anisotropic crystalsare unidirectional in the easy magnetization direction, so a strong magnet can be made only by magnetizing from the easy magnetization direction of the arrow.
