Axial and Lateral Search Coils

These Search Coils consist of 5000 turns of very fine copper wire on a bobbin fixed at one end of fiber glass board (electrically insulated and non magnetic) and on the other end two 4 mm socket terminals are fitted. They can be used to determine field strengths or flux density inside the air gap of magnets or solenoids. An a. c. or d. c. signal can be applied to the search coils to study the effect of interacting magnetic fields.

The Axial Coil has the coil mounted with its axis parallel to the axis of the PCB board.
The Lateral Coil has the coil mounted with its axis at 90 degrees to the axis of the PCB board.

Signal Generator also required for use (B8G85779 or similar).
The coils are available to order separately:

Lateral Search Coil – R07038
Axial Search Coil – R07037
