Magnetising & Demagnetising coil

Description

A wooden table supports a plastic ring wound with three coils of 5, 10 and 20 turns of insulated copper wire, connected to terminals on the base.

Description

Non-magnetic metal pillar with carbon steel point, on stable base, overall height 110 mm

Description

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.

Description

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.
