We have designed, fabricated, and made operational an ex situ cantilever beam magnetometer (CBM), which is versatile in the sense that it can measure most of the magnetic properties of a material in all probable shapes. The working principle of a CBM is discussed considering the magnetic torque into the beam theory. The individual components of the instrument are described in details and experiments were performed on the bulk materials, pellets of nanoparticles, ribbon samples, and thin films, and the magnetization, magnetostriction, and magnetocrystalline anisotropy were studied. This magnetometer is inexpensive, but versatile and would be suitable for the research as well as teaching laboratories.
我们设计、制造并投入使用了一种非原位悬臂梁磁力计（CBM），它具有通用性，能够测量各种可能形状材料的大部分磁性能。基于梁理论考虑磁转矩来讨论CBM的工作原理。详细描述了该仪器的各个组件，并对块状材料、纳米颗粒小球、带状样品和薄膜进行了实验，研究了它们的磁化强度、磁致伸缩和磁晶各向异性。这种磁力计价格低廉，但功能多样，适用于研究实验室和教学实验室。
