Quick Answer: The Axial and Lateral Search Coils are 5000-turn coils on fibreglass boards, one axial and one lateral, for determining field strength or flux density in the air gap of magnets or solenoids.
Last updated: October 2026
Key Features
5000 turns of very fine copper wire on a bobbin
Fibreglass board, electrically insulated and non-magnetic
Two 4 mm socket terminals at the other end of the board
Axial coil: axis parallel to the board's axis
Lateral coil: axis at 90 degrees to the board's axis
Take an a.c. or d.c. signal for studying interacting magnetic fields

About This Product
The search coils are used to determine field strengths or flux density inside the air gap of magnets or solenoids. Applying an a.c. or d.c. signal to them lets the effect of interacting magnetic fields be studied. The two versions differ in coil orientation relative to the board.
Frequently Asked Questions
Q1. What is the difference between the axial and lateral coils? The axial coil is mounted with its axis parallel to the axis of the board. The lateral coil has its axis at 90 degrees to the board's axis.
Q2. Can the coils be bought individually? Yes. The Axial Search Coil and the Lateral Search Coil are available to order separately.
