<p>PROBLEM TO BE SOLVED: To provide a magnetic element wherein permeability is hard to decrease and high DC superposing characteristic is obtained, when a magnetic field applied to a core is increased in accordance with a current applied to a coil. SOLUTION: The magnetic element 1 includes a core 2 having a ring shape, a coil 4 which is wound around the core 2 and excites an internal magnetic fieldΦ1 containing magnetic flux penetrating the inside of the core 2, and permanent magnets (external magnetic field applying means) 6, 6 for applying an external magnetic fieldΦ2 containing magnetic flux which is almost rectangular to the magnetic flux of the internal magnetic fieldΦ1.</p> |
