Hard and Soft Magnetic Materials

Permanent materials are also called hard materials. Permanent magnets utilize rare earth magnetic materials in signaling devices and computers. Signaling devices have forces up to ten times of that ordinary magnet and they have high durability. Magneto-optic magnets are used for memory system in computers, are spot-size magnets which are made with thin wafers. Hard magnets are used in data storage analog and digital also. Soft magnetic materials are easily magnetized and demagnetized magnetic materials. The applications of soft magnetic materials were divide into two main categories- AC and DC. In DC applications the material executes an operation when magnetized and then demagnetized at the end of the operation. In AC applications the material will be endlessly cycled from being magnetized in unique direction to the other, through the period of operation. Soft magnets are used in signal transferring.

Magnetic materials that hold their magnetism even after being magnetized are defined as permanent magnets or hard magnets. It indicates to those matters which have got a fundamental coercivity of more than ~10kA/m. Magnets like cesium-cobalt magnets (SmCo5) and samarium-cobalt magnets (CeCo5) are casted from annulled metals and other chemical compounds. These magnets have intrinsic forces up to 2.2 million A/m. and hard magnetic materials are largely applied in quantum devices. Soft magnetic materials are used in electromagnetic pole-pieces to raise the fields formed by the magnet. Soft magnetic materials are also used to activate solenoid switches. Mostly permanent magnet devices will use soft magnetic materials to channel fluidity lines or provide a return path for magnetic fields. Soft magnetic materials are used in magnetic field screening.
