Student Manual

The experimental objective is to use a Hall sensor and to find the field and magnetization of a magnet. We will also gain practical knowledge of magnetic field transducers, hard disk operation and data storage, visually and analytically determining the relationship between induced EMF and magnetic flux, and indirectly measure the speed of a motor.
