Lateral Search Coil

The Lateral Search Coil is a precision physics accessory designed for investigating magnetic fields, flux density, and electromagnetic induction in educational laboratories. It is specifically configured to measure the transverse component of a magnetic field, making it an ideal complement to axial search coils in comparative field studies.

The coil consists of 5,000 turns of very fine copper wire wound onto a bobbin, securely mounted at one end of a fibreglass board. The fibreglass support is electrically insulated and non‑magnetic, ensuring accurate measurements without interference. At the opposite end of the board, two 4mm socket terminals provide reliable connections to standard laboratory instruments.

In the lateral configuration, the coil axis is mounted at 90° to the axis of the PCB board. This orientation enables students to examine how magnetic field strength and induced emf vary with direction, reinforcing the vector nature of magnetic fields. Both AC and DC signals can be applied to study interacting magnetic fields and electromagnetic induction effects.
