Alnico Bar Magnet, 150 x 15 x 10mm Subcategory_Anatomy Models Demonstrates the full light-to-electricity-to-motion chain

Demonstrates the full light-to-electricity-to-motion chain through a solar cell

5 ohms and 9A with oxidized constantan winding on a vitreous-enameled tube and three binding posts

the broad pole faces giving a flatter field profile than narrow U-shape models

covering refraction shapes for a complete optics lab kit

drawing 4-6V DC through 4mm sockets to demonstrate how current produces a concentrated magnetic field
