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 apparatus spins an electrically charged brass wheel spin, without the aid of a motor.
When the wheel electrified by a voltage source (battery), the slotted brass disc sets up eddy currents throughout the structure.
This electricity is then attracted to 4 strong neodymium magnets, causing the wheel to spin.
Bar magnet pair with keeper
Alnico Bar Magents (Pair) with spacer and keepers. Supplied in cardboard boxes Actual bars may be different size than stock photo.
Bar Magnet Alnico (Pair) Size are mentions below which we have :-
38 x 10 x 5 mm (1.5")
50 x 10 x 5 mm (2")
75 x 10 x 5 mm (3")
100 x 10 x 5 mm (4")

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 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.
