Circular Helmholtz coil DXWJ series

copper

No magnetic moment coil through several groups of coils to a certain geometric structure of the installation, and through each group of a certain number of coil turns and a certain current direction, so that the magnetic field rapidly decays coil, the coil moment of zero. No magnetic moment coil has a very prominent advantage: the work of a certain distance away from the environment will not produce magnetic interference, which for multiple systems work simultaneously has a very important significance; In addition, the non-magnetic moment coil will not magnetize the more recent Magnetic material, and therefore will bring no additional torque in this area of the magnetic torque error.
