An acrylic assembly holding a 100 turn coil with 4mm socket connections which can slide on a 300mm long, 15mm dia. acrylic tube. A small cylindrical magnet can be dropped down the tube so that a pulse of electricity is generated in the coil as it passes through. An oscilloscope is used to monitor the pulse and measure its amplitude. At different speeds the amplitude varies and can be used by A-Level students to investigate Faraday’s Law while revising equations of motion to determine the speed.
