Solenoid has the advantages of good uniformity, small size, and high magnetic field. It can output AC/DC magnetic field, Current and magnetic field has a good linear relationship. Apply to the institute, institutions of higher learning and company do material or magnetic detection experiment, applied to materials, electronics, biological, medical, aerospace, chemical, physical, and other disciplines.
Generating AC magnetic fields with solenoids has a great advantage over Helmholtz coils in that it has a compact size and a small inductance, making it easy to generate high-frequency magnetic fields.
Continuous pulse magnetic field and AC magnetic field are similar in design. In recent years, the application of continuous pulsed magnetic fields gradually increased, Dexinmag company has completed many cases, praised by users.
The non-magnetic moment solenoid is composed of two sets of solenoids nested in a nested manner, and through a certain number of coil turns of each group of coils and a certain current direction, the magnetic field outside the solenoid is rapidly attenuated. The total magnetic moment of the tube coil is zero.
