Depending on the cause of the demagnetization and the duration of the condition, it is possible to repurpose the magnetic material and restore the lost magnetism. One method for restoring the permanent magnet is to use a solenoid. When current is activated through the coiled wire of the solenoid, it may be sufficient to restore the magnetic field of the magnet. The demagnetization can adversely affect the function of the magnet and the use of the magnet as a component. Therefore, it is very important to identify and design magnetic components to avoid physical conditions that may demagnetize.
