Variable Magnetic Field Coil

The Variable Magnetic Field Coil is designed for practical investigations of the magnetic field generated by a solenoid. Its adjustable construction allows changes in magnetic-field behaviour to be investigated by varying the effective configuration of the coil.

The apparatus consists of a solenoid wound with enamelled copper wire on a clear acrylic tube. The transparent tube provides good visibility of the coil arrangement and internal experimental region while also serving as a stable non-magnetic support for the winding.

A distinctive feature of the apparatus is its movable solenoid ends. The extreme ends can be repositioned, enabling the effective magnetic-field arrangement to be varied during experiments.

Micro Technologies provides 4 mm electrical sockets for connecting the solenoid to a suitable controlled current source. These standard laboratory connections simplify integration with compatible power supplies and measuring instruments.

When current flows through the solenoid winding, a magnetic field is generated along and around the coil. The apparatus can be used to investigate field direction, relative field strength, current effects, and changes associated with the adjustable coil configuration.

The coil measures approximately 60 mm in diameter and 350 mm in length, providing an elongated solenoid arrangement suitable for magnetic-field experiments.

Suitable magnetic compasses, field probes, or compatible measuring instruments can be used with the apparatus according to the required investigation. By changing the current or adjusting the movable ends, variations in the resulting magnetic field can be examined.

The combination of a clear acrylic former, enamelled copper winding, movable end arrangement, and convenient electrical sockets makes the Variable Magnetic Field Coil a versatile apparatus for repeated magnetism and electromagnetism investigations.
