Rotating Coil (0830)
Specifications : Dimensions: approx. 20 x 20 x 35 cm. Weight: approx. 3 kg. Rotating Coil is an interesting device to study Faraday-Neumann-Lenz’s law. Generation of currents when a coil rotates in a magnetic filed is a basic concept of hundreds of crucial applications in physics, engineering and everyday life (e.g. this is the principle of the dynamo). This apparatus is comprised of a suspended coil free to rotate and magnets beneath; a crank will help to rotate the coil; two 4 mm sockets allow to measure the differential voltage generated by the coil or to mount a circuit. The Rotating Coil has a sturdy base with rubber feet and a security shield for safe usage. LAWS & PRINCIPLES INVESTIGATED : • Faraday-Neumann-Lenz’s law
• Earth magnetic field.
