FunctionFor the experimental determination of M/H (magnetic fields) by the method of Gauss. A meter stick should be attached to two of the (4) support rods and a bar magnet provided (65mm long , 6 mm square).
The angle of declination would be determined by watching the reflection of the scale on the mirror with a scope.
