Laplace Rail for Magnetic Field Demonstration, 11.75 x 3" Plastic Labware_Plastic Burettes built to travel between fieldwork

built to travel between fieldwork sites without damage

Standard rheostat at 16 ohms and 4A with oxidized constantan winding on a vitreous-enameled steel tube

suitable for securing tubes and flask necks in general laboratory assemblies

this wooden simple-machine model lets students measure input effort against output splitting force at different wedge angles

Laplace Rail for Magnetic Field Demonstration, 11.75 x 3" Plastic Labware_Plastic Burettes built to travel between fieldworkOpen Laplace rail with a free moving conductor and 4mm sockets, letting students watch the wire travel along the rail as roughly 3A of current crosses the magnetic field.
