Comprising iron U-shaped core of circular section, with armature and carrying hook.
Wounded with insulated copper wire and provided with connectors for use on 4-6 volts D.C.
This demonstrates the action of electric current on a magnet.
A cobalt steel needle with agate bearing supported by pivot is mounted on a plastic base and surrounded by rectangular frame fitted with terminals.
For investigating the magnetic field associated with a solenoid coil.
Coil size 51 x 92 mm.(diameter x length) approx.,diameter of wire 1.5 mm.
Magnetic field Demo, long solenoid
Consist of a closed transparent box with a transparent tube through the center.
The box contains iron filings and silicon oil.
When one or more cylindrical magnets are inserted into the central tube, the filings are attracted and line up along the field lines in all dimensions With Cylindrical Magnet.
For ordinary magnets, iron bars, strips etc.
Consists of a 250 mm long solenoid wound with insulated copper wire and mounted on a base, with switch and 4mm terminals.
Operating voltage is 12 V A.C. or D.C. At 6A max.
