A. Apparatus to Show Force on a Conductor in a Magnetic Field
Comprising a strong U-shaped magnet and a pair of brass rails with 4mm socket terminals. A brass axle with plastic discs is free to roll along the rails and completes the electrical contact between them.
When the axle is placed on the rails between the poles of the magnet, and a power supply unit is connected, the axle is repelled and rolls along the rails away from the centre of the magnetic field.<return/>Dimensions: 175 x 60 x 58mm

B. Lenz Law Demonstration Kit using Aluminum Tube
The Lenz’s Law Kit provides the necessary tools to discover concepts involving Farady’s Law, magnetism, and eddy currents in addition to the Lenz’s Law. The pipes of differing materials excel at demonstration the magnet braking force in action as the two magnets are simultaneously dropped through each of the aluminum and clear plastic tubes. A dynamometer attaches to suspend the Lenz’s Las apparatus so students can quantitatively measure the additional force as the magnet drops through the conductive tube. Supplied with instructions.
Kit includes: Lenz’s law apparatus Dynamometer 2 magnets
CP00052733 C. Eddy Current Kit
For providing a qualitative practical demonstration of Lenz’s law. Comprising a copper tube 320 x 15mm (l x d) together with a pair of cylindrical ‘plugs’. The plugs are identical in appearance and mass but one is plain steel and one is a powerful neodymium magnet. The time taken to fall is greatly extended as a result of the eddy currents induced in the copper generating a magnetic field which opposes the movement of the magnet. Supplied with a pair of plastic caps to provide self contained storage.
