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.
A former with terminals and engraved circle marked 0 – 180° – 0 figured every 45°, wound with 30 turns of insulated copper wire, complete with a magnetic needle 75 mm long and a pivot for the needle.
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.
Magnetic field Demo, long solenoid
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.
A kit of magnets and accessories in a storage tray.
