4-Case 95% Ethanol High-Concentration Histology Alcohol, 1 Gallon Each Diameter_300mm Demonstrates electromagnetic induction and Faraday's

Demonstrates electromagnetic induction and Faraday's law by stepping DC input into 25mm high-voltage sparks across adjustable electrode rods on an open chassis

the larger geometry pushing pole separation wide enough that field lines extend visibly beyond the magnet body for filing maps

and material science exploration

5-meter precision optical bench

and a distinct euhedral crystal habit
