SB120 Coil PlatformDetailed product description：

The SB120 coil platform is used for physics education experiments in universities.

Among them, the SB120 coil platform and the SB120/1 sample platform can respectively test and study the magnetoresistance and conductor/semiconductor resistivity of magnetoresistance films.
The experimental platform consists of a chassis with a 360 degree scale, a lining plate that can rotate 360 degrees inside the chassis, a sample platform (adjustable in height) mounted on the chassis, and a four probe probe mounted on the sample platform, forming the SB100/1 sample platform.

The SB120 coil platform mainly adds two Helmholtz magnetic field coils of the same type, which are respectively placed on both sides of the sample platform and fixed on both sides of the rotatable 360 º backing plate. The sample platform is located at the center of the magnetic field, and when it is powered from 0-60V/5A, it can ensure the generation of a magnetic field of 0-150 Oersted.
This experimental platform provides convenience for the testing and research of the tested sample under magnetic and non magnetic field conditions.
