Claims

[Scope of utility model registration request]

A pair of coils are wound around each core and arranged approximately parallel to each other, and a pair of coils is arranged on the end face side of each coil to apply a common magnetic bias to the pair of coils, and to control the magnetic field acting on each coil. Consists of a single permanent magnet that has varying degrees of strength.
A coil device in which the permanent magnet is provided so that its winding position in an assembled state can be adjusted.
