Embodiment Construction
[0022] The present invention will be further described below by taking a magnet with a 4-coil structure as an example.
[0023] figure 1 with figure 2 The magnet coil shown is made of flat copper enameled wire, and the cross section of the enameled wire is 1mm*4mm. Coil 1 is wound with 10 layers, each layer has 12 turns; Coils 2, 3, and 4 are wound with 6 layers, 4 layers, and 3 layers respectively, with 12 turns for each layer, so that the inductance of the four wound coils is relatively close. The ratio of the maximum inductance to the minimum inductance is less than 2. The winding directions of adjacent coils are opposite, which not only facilitates the connection of parallel coils, but also reduces the insulation requirements between adjacent coil layers. The inner cavity of the bobbin 0 is the experimental space, where a strong magnetic field is generated, and the diameter of the cavity is 12mm.
[0024] When the coil is wound, the coil bobbin 0 rotates around its ax...

Description
technical field [0001] The invention relates to the field of strong magnetic fields in physics and the field of strong pulses in electrical engineering, in particular to a device for generating pulsed strong magnetic fields by using capacitor energy storage type power supply discharge and a manufacturing method for magnets. It is a non-destructive pulse strong magnetic field generating device. Background technique [0002] As a special and extreme scientific research condition, a strong magnetic field has a strong impetus for breakthroughs in scientific research, and a pulsed strong magnetic field is easier to obtain a high-intensity magnetic field than a steady-state strong magnetic field. Therefore, developed countries in the world have established their own pulsed strong magnetic field laboratories to generate pulsed strong magnetic fields and provide strong magnetic fields for scientific research in various fields. The pulsed strong magnetic field in the present inventi...
