LMEC-14 Apparatus of Magnetic Damping and Kinetic Friction Coefficient

Short Description:

Product Detail

Product Tags

Magnetic damping is an important concept in electromagnetics, which has been widely used in various fields of physics. However, there are few experiments to directly measure the magnetron force. Fd-mf-b magnetic damping and dynamic friction coefficient tester uses advanced integrated switch Hall sensor (Hall switch for short) to measure the sliding speed of magnetic slider on the inclined plane of non ferromagnetic good conductor. After data processing, the magnetic damping coefficient and sliding friction number can be calculated at the same time.


1. Observe magnetic damping phenomenon, and understand the concept and applications of magnetic damping

2. Observe sliding friction phenomena, and understand the application of friction coefficient in industry

3. Learn how to process data to transfer a nonlinear equation into a linear equation

4. Acquire magnetic damping coefficient and kinetic friction coefficient
