摘要

A system for emitting a controlled magnetic field, the system comprising: an electromagnet (1, 11) having a magnetic core (5), the magnetic core comprising a ferromagnetic or ferrimagnetic material; storage means for storing the electromagnet when the electrical power is switched off; andheating means for heating the magnetic core, the heating means being operable to heat the magnetic core above its Curie temperature for storage of the electromagnet by the storage means while the electrical power of the electromagnet is turned off.
