Lenz's Law Apparatus Lenz's Law Apparatus
501-10
 
Consists of two metal rings connected by an aluminum beam that can rotate freely on a support. One of rings is a closed loop, the other has an opening for comparison. When a bar magnet moves into or out of the loop the magnetic flux will change. According to Lenz's Law, a current will be induced in the loop to oppose the change. Students can verify the law by analyzing the movement of the loop.

This unit is used to measure the current traveling through a conductor. To explain the reaction and its rule of a loaded conductor in the magnetic field, in order to formulate a clear conception of magnetic induction.
Lorentz Force Demonstrator
63412 

Demonstrates the motion of electrons in a magnetic field, and determines the charge-to-mass ratio of an electron (e/m).
Accelerating voltage is continuously variable between 0 and 250V.
Polarity of voltage on deflecting plates and polarity of electromagnet can both be reverted.
Magnetism Torch
S307-4
Moving the torch at horizontal direction a few second, then the torch will be light on. As the torch is shaken the magnet inside passes through a copper coil producing electricity. The electricity is stored by a capacitor for use when light is needed.
