Description
and 125mm in a plastic wallet with keepers
U-magnet and brass-rail apparatus that demonstrates the motor effect
and the triboelectric series
Used to read spectral lines against a 400-700nm graduated scale
producing distinct audible pitches at varying spin speeds to relate rotational frequency to perceived sound frequency
Variable Gap Magnet for Physics Demonstrations Base Size_8 x 5" and 125mm in a plasticAdjustment screws (3 x 1 inch) on a metal base position two neodymium magnets, varying the pole gap from 0. 4 to 8. 5cm and field strength from 100 to 7500 Gauss across the working volume.
