MAGNETIC PLOTTING COMPASS

Magnetic compasses were used for navigation for hundreds of years.
Students can get a clear understanding about how a magnetic compass works, with the Earth like a giant magnet, surrounded by a huge magnetic field, and two magnetic poles which lie near the North and South poles. The magnetic field of the Earth causes a magnetized ‘needle’ of iron or steel to swing into a north-south position when suspended.
The plotting compasses are used to show the direction and the shape of a magnetic field.
Our plotting compass has both the faces of clear glass having two orthogonal cross-lines, in an aluminum frame.
The dial of the compass only shows the N, S, E and W directions.
It is about 18mm in diameter.
