Cut-away section on this chloroplast model exposes grana stacking

deflecting a pivoting cobalt-steel compass needle inside a rectangular conductor frame to show that current generates a magnetic field

and field magnet for direct observation as students trace how current produces rotation in a closed magnetic circuit

the diverging curvature paired with low mass for ray-box mounts and lightweight optics setups

Student pulley demonstration set with a range of pulleys for mechanical-advantage and force-multiplication comparisons
