this Alnico U-shape carries 45mm pole spacing for compact-bench field demonstrations and motor-effect setups

generating opposite charges along its length to compare negative and positive triboelectric behavior side by side

letting students see the plate stack and watch electrolyte action through the side wall

Hands-on fold-and-fault model with manipulable rock strata
