Description

technical field [0001] The present application relates to the electromagnetic field, in particular to an electromagnetic coil assembly and electromagnetic equipment. Background technique [0002] In order to make full use of the three-dimensional magnetic field, the industry has launched a 3D electromagnetic coil assembly, including a support, a magnetic core, a base, and a 3D electromagnetic coil. The 3D coil surrounds the support, and the magnetic field direction of the 3D coil is in the x-axis direction of the magnetic core, The y-axis direction and the z-axis direction are orthogonal to each other. However, in the prior art, various structural elements (such as the support part and the base, the magnetic core and the support part) are assembled by bonding, which not only complicates the manufacturing process, but also tends to cause problems such as poor bonding and assembly gaps. Contents of the invention [0003] Embodiments of the present application provide an ele...
