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.
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
A kit of magnets and accessories in a storage tray.
Contents :
1. One Horseshoe magnet, 100 mm, with keepers.Two ceramic bar magnets, 75 mm long.
2. Three ceramic ring magnets, 38 mm diameter
3. Two plotting compasses clear both sides, 19 mm diameter
4. One lodestone specimen.
5. One pack Iron Filing.
6. One each strip of Iron, Aluminium, Zinc and Copper metal.
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.
This apparatus demonstrates the magnetic field patterns associated with the different shapes of current carrying conductors.
Comprises three conductors, each of different shape/configuration – straight rectangular, circular loop and solenoid all mounted on a plastic base.
Each configuration is provided with a pair of 4 mm sockets to connect them to a low voltage DC power source, with output current not exceeding 5A With the included iron filings and 8 magnetic compasses, you can investigate the associated field and flux patterns.
