Description

Helmholtz Coils are a special arrangement of coils that are placed in such a way as to generate a very uniform magnetic field between them when a current is applied. The strength of the magnetic field is proportional to the number of turns in the coils and the current applied to them. The Helmholtz Coils setup consists of two field coils mounted on a track to provide a uniform magnetic field between the coils. The proper separation for Helmholtz coils is marked on the track. A pair of precision coils and 400 turns of wire are wound on heat resistant former of about 150 mm diameter.

Description

Revolving in pivots, with a graduated quadrant, rotatable on a base marked every 45°.

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

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.
