Variable Gap Magnet for Physics Demonstrations Base Size_8 x 5" Used to read spectral lines

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

paired with 4mm sockets so iron-filing patterns can be mapped around a current-carrying conductor for Oersted's experiment

Demonstrates Hooke's Law

Sized for compact classroom display

Variable Gap Magnet for Physics Demonstrations Base Size_8 x 5" Used to read spectral linesAdjustment 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.
