Laplace rail with carrying conductor Fitted with 4mm sockets 11.75" long, 3" wide, 2" tall For demonstrating magnetic fields on free moving current carrying conduction placed on to current elements Perfect for physics experiments

Current required for movement is approximately 3 Amp. Apparatus fitted with 4mm sockets. For demonstrating the action of magnetic field on free moving current carrying conductor placed on to current elements. Calculation is done resulting from the displacement of the conductor due to electromagnetic force. W = B.I.I.D = If. Apparatus measures 11.75" long, 3" wide and 2" tall. Carrying conductor pieces measures 3" long and 0.25" in diameter.
