Linearity coil

A variable linearity coil has a coil which is wound around a magnetic core, a permanent magnet for charging a bias magnetic field to the magnetic core, and a magnetic field adjusting coil for adjusting the bias magnetic field. The coil and the magnetic field adjusting coil are respectively disposed horizontally such that an axial line of each of the coils lies perpendicular to lead terminals to which terminal ends of each of the coils are connected. The coil, the magnetic field adjusting coil, and the permanent magnet may be contained in a casing and the terminal ends of each of the coil and the magnetic field adjusting coil are connected to lead terminals which are embedded into the casing.

Variable linearity coil

A variable linearity coil has a coil which is wound around a first core, a permanent magnet for charging a bias magnetic field to the first core, a bias magnetic field adjusting coil which is wound around a second core, and an electrically insulating base for mounting thereon the coil, the permanent magnet, and the magnetic field adjusting coil. The first core and the second core are placed one on top of the other with a non-magnetic and shock-absorbing spacer in between. Alternatively, the first core and the second core may be placed one on top of the other with a non-magnetic spacer in between, and a combination of the first core, the second core and the non-magnetic spacer is mounted on the base with a shock-absorbing spacer between the combination and the base.
