The magnetic movements of a bar magnet can be compared quantitatively and the relative field intensities at various distance from a bar magnetometer._x000D_
A highly sensitive compass box (with a permanent magnet) is mounted at the center of a non-magnetic wooden base about one meter long, a metric scale extending outward from each side of the compass box for observing the position of the magnet tested. The compass direction is indicated in degrees. It consists of 18 mm thick laminated board (both side sunmica) with dimensions 40” x 5” with aluminum cup at the center for holding compass box.
