Plastic bobbin with 2, 50 and 500 turns of insulated copper wire and rotatable on vertical axis is mounted on a moulded plastic base, with leveling screws and four terminals, with magnetometer mounted at the center of the bobbin.
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.
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.
