Silicon Tubing, 5 x 1mm Safety Supplies_Eye Protection Tangent-galvanometer instrument that derives current

Tangent-galvanometer instrument that derives current absolutely from compass-needle deflection against Earth's horizontal field

Pole gap on this Alnico U-shape concentrates the field strongly enough to drive a Lorentz-force motor demonstration or to anchor a swinging-pendulum eddy-current setup

Spring-clipped metal frame on a mounting rod grips gratings

each strip 5 inches long

Foundational 12-slide introductory set covers plant and animal tissue preparations for first-year microscopy work in general biology classrooms

Silicon Tubing, 5 x 1mm Safety Supplies_Eye Protection Tangent-galvanometer instrument that derives currentAutoclavable and inert, silicon tubing in a 5 by 1 mm profile supports biology laboratory runs where cross contamination between experiments matters.
