Solenoid Introduction of Solenoid: Solenoid is a kind of important tool for generating magnetic field, it has the advantages of simple structure, convenient use, the magnetic field in the axial direction after power on, and the magnetic field keeps the everlasting linear relationship with electric current, when length has a larger proportion with diameter, it has good homogeneity near the magnetic field center, and the larger the ratio is, the wider the uniform area will be, it is very suitable for the straight long sample magnetization. Multilayer solenoid can increase the magnetic field strength, the stronger magnetic field is, the stronger the power would be. Heat dissipation should be considered when long time use, even the protective action of electromagnetic force should be considered.
