WE-LFA-6X300
Coil Array – Water-Cooled
Pulsed Magnetic Field Generation for Scientific Applications
Woodruff Engineering’s 6-Coil Linear Array System delivers precise, extended magnetic field control along a 1.1-meter working volume, making it ideally suited for applications requiring uniform axial fields or controlled field gradients over substantial sample lengths. Built around six water-cooled copper coil assemblies positioned at 200 mm intervals, the system generates highly stable magnetic fields within a 302 mm diameter bore, providing a versatile platform for materials testing, biological studies, and industrial process development where extended field exposure regions are essential.

Key Features
Extended Axial Field Control
Six independently controlled coils enable uniform field zones, linear gradients, or custom axial field profiles across a 1-meter working length. Ideal for materials testing requiring extended field exposure regions.
High-Field Pulsed Operation
Water-cooled copper coils deliver up to 200 mT fields with 10-minute continuous pulse capability. Integrated thermal management maintains field stability during extended experimental runs.
Flexible Field Shaping
Independent current control per coil allows researchers to configure uniform zones, linear gradients, or custom field profiles. Software-programmable patterns enable complex experimental protocols.
Through-Bore Sample Access
302 mm clear bore diameter accommodates large samples, fixtures, and multi-sensor arrays. Dual-ended access simplifies sample loading and instrumentation integration.
Production-Ready Build
Precision-wound coils with factory calibration data. Modular aluminum frame ships assembled or flat-packed. Complete installation documentation, field mapping reports, and current-to-field conversion tables included.

Why Choose THE WE-LFA-6X300?
CUSTOM-MADE • At Woodruff Engineering, we work with you to design a coil array perfectly suited to your needs.
HIGHLY CONFIGURABLE • Adjustable coil positions and customizable dimensions give you the precise field control you need. Control coils individually or in parallel depending on your application.
RELIABLE PERFORMANCE • Our water-cooled coil arrays are built to last. Even after thousands of thermal cycles, your array will continue to generate a precise, uniform field.
LARGE-VOLUME WORKING FIELD • Ideal for testing full-scale components that smaller systems simply can’t accommodate.
Target Applications
Component Testing
Expose sensors, actuators, PCBs, and magnetically sensitive electronics to precisely controlled, repeatable field environments to verify performance, identify susceptibilities, and validate EMC compliance under realistic operating conditions.
Device Calibration
Generate stable, well-characterized magnetic fields with traceable current-to-field relationships, providing a reliable reference environment for calibrating magnetometers, Hall probes, flux sensors, and other field-measuring instruments to metrology-grade standards.
Materials Testing
Subject structural materials, composites, and functional coatings to sustained or pulsed magnetic fields — alone or combined with thermal loading — to characterize magnetic properties, Lorentz force effects, and field-induced changes in mechanical behavior over an extended working volume.
Crystal Growth
Apply controlled axial or gradient magnetic fields during the growth process to suppress convective flow in molten material, enabling the production of higher-purity, more structurally uniform crystals for semiconductor, optical, and research applications.
Magnetophoresis
Use programmable field gradients along the bore axis to exert controlled forces on magnetic or magnetically labeled particles in solution, enabling the separation, concentration, or directed transport of biological cells, nanoparticles, or colloidal materials for research and biomedical applications.
