1.5m Metal Optical Bench Mechanics_Kinematics 2A with constantan winding on

2A with constantan winding on a vitreous-enameled steel tube and a nickel-plated phosphor-bronze sliding contact

This is highly useful apparatus for the wave demonstration

this large earthworm dissection model reveals segmentation

Designed to generate and detect ultrasonic waves above the audible range

portable enough for mobile demonstrations of current-driven magnetic field strength
