A national defence research and engineering programme needed an electro-magnetic device fitted to trawl tanks that could generate the magnetic disturbances needed to safely trigger magnetically-fused mines ahead of the vehicle.

Electro-Magnetic Mine-Clearance System for Trawl Tanks
11 Aug 2026An electro-magnetic device fitted to trawl tanks to trigger magnetic mine fuses safely.
The main challenges were
- Magnetic mine clearance requires generating a precise
- controllable magnetic field from a moving armoured vehicle
- with the electronics themselves surviving the same battlefield conditions the trawl tank is designed to clear a path through
The system needed to
- Deliver an integrated electro-magnetic assembly that lets a trawl tank crew trigger magnetically-fused mines from inside the vehicle
- replacing manual detection and disposal with a safer
- controller-driven process
The solution included
- Dynalog supplied the Electro-Magnetic Device (EMD) assembly fitted to trawl tanks, combining a Power Supply Unit, an Electronic Controller Unit, and A-Coil/P-Coil magnetic field generators into one integrated system
- The Power Supply Unit conditions and delivers the power the coils need to generate a strong, controllable magnetic field, while the Electronic Controller Unit lets the crew manage field strength and timing from inside the armoured vehicle rather than exposing personnel outside it
- The A-Coil and P-Coil are positioned to generate the magnetic disturbance needed to trigger magnetically-fused mines directly in the vehicle's path, clearing a safe corridor as the tank advances
- Every component in the assembly is built to survive the same shock, vibration, and battlefield conditions the trawl tank itself is designed to operate in, so the mine-clearance electronics remain dependable exactly when they're needed most
Conclusion
Mine clearance is inherently dangerous work — purpose-built electronics that let crews trigger mines safely from inside an armoured vehicle is exactly the kind of engineering that protects lives in the field.
