Demonstrate Magnetic Field Lines using this unique device – its transparent housing is perfect to place on an overhead projector for the entire class to see. The Diamagnetic Levitation Apparatus is an inexpensive device which uses graphite as the diamagnet. Individual magnets are available in a variety of shapes and sizes or you could try our Magnetic Equipment Set with over 24 dozen components.
Apparatus for demonstrating repulsion forces between magnets. Two ring magnets facing each other with identical poles are slid on a rod.
Base: approx. 100 mm dia.
Rod: approx. 100 mm x 30 mm dia.
Weight: approx. 410 g

The Oersted Device demonstrates how a magnetized object, in this case a needle, is deflected by the presence of an alternating magnetic field, produced here by an electric current. The magnetic needle has two distinct poles and a length of ...
This solenoid allows you to magnetize and demagnetize ordinary magnets or iron bars in addition to conducting inductance experiments. The rugged unit consists of insulated copper winding mounted on a base with 4mm sockets and a switch.
