Magnetic Demo

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. 8" x 6" x 3"
Magnetic Field Demonstrator Magnetic Field Demonstrator

A quick and clean way to visualize magnetic fields.
The unit is a transparent acrylic case that holds iron filings in a fluid of proper viscosity. The unit can also be placed on an overhead projector for classroom demonstration. Magnetic bar/shoe piece is not included.
Measures 8 x 4-1/2 x 3/8", 11 oz.
3D Magnetic Field Demonstrator 3D Magnetic Field Demonstrator
1257-1 
This device allows students to observe magnetic fields in 3D and 2D views. It consists of two half hexagonal acrylic containers with metal filings. The two parts, connected with hinges, can be swung open or closed. A strong bar magnet is placed in the concavities of the  containers to reveal the cross section of a magnetic field.
