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.
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 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.
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.
