Magnetic Needle on Stand
Magnetic Needle on Stand
Our Magnetic Needle provides a simple demonstration model of how a compass works.
It is constructed simply of a magnetic needle finely balanced on a needle on top of a supporting stand.
The pointer is alternately coloured in red and blue, allowing the user to
easily identify the direction of North and South Poles.
