Magnet Domains & Magnetization: Magnetic Materials
Magnet Domains & Magnetization: Magnetic Materials
Purpose
To demonstrate by analogy the different magnetic domains within a non-magnetized and
subsequently magnetized ferromagnetic material.
Description
An array of small compass needles illustrates the domain structures within a ferromagnetic
material.
WARNING: Many students already confuse the north and south poles of a magnet to be positive and negative charges (respectively!). This apparatus reinforces this misconception!!!
Equipment
Magnetic Domain Model; small, strong magnet
Support Equipment
Overhead Projector
