Brass Slotted Mass Set with Hanger, 8 x 25g Base_Octagonal and commutator assemblies for direct

and commutator assemblies for direct observation of each component

this metal-framed bench demonstration board uses variable resistors and switchable inputs to show how a meter measures V

the wider bore accepting full-size bar magnets while AC current drives the alternating field that rotates domains for demagnetization

5 inch base for precise angle measurement during wave-optics investigations

3 inches for condensers and flasks
