From passive magnetics to
active magnetic control
FluxWorx is developing the Magnetic Transistor, a fundamental shift in how we interact with the electromagnetic force. By moving from fixed geometry to active reluctance modulation, the architecture aims to enable a new class of motors, transformers, and power systems.
Active Reluctance Modulation
The Magnetic Transistor is designed to use a small control input to influence a much larger magnetic operating condition. Just as a silicon transistor uses a small control current to steer a large flow of electrons, the FluxWorx architecture aims to modulate the reluctance (magnetic resistance) of a flux path in real-time.
How Differential Flux Steering Works
By actively biasing selected regions of a coupled magnetic structure, Differential Flux Steering (DFS) aims to change the effective reluctance distribution and reshape how flux density is distributed.
Steer Flux
Guide magnetic operating conditions toward the desired working region on demand.
Shape Waves
Shape magnetic transitions to reduce abrupt waveform behaviour, torque ripple, acoustic noise, and EMI-sensitive edges.
Clamp Surges
Rapidly shift magnetic operating conditions to limit energy transfer during the early stages of a fault.

FluxWorx aims to extract more useful performance from magnetic systems through control, rather than simply adding more material.
Material Substitution
We aim to replace expensive, price-volatile materials (like Neodymium and heavy copper shielding) with cheap, abundant materials (Steel, Aluminum) combined with advanced Control IP.
Asset Utilization
By reducing unwanted flux behaviour, thermal stress, and dynamic losses, we aim to allow smaller transformers and motors to do the work of larger ones.
Lifecycle Cost
By eliminating mechanical stress (torque ripple, inrush shock), potential benefits include improved equipment lifetime and reliability margins (subject to application-specific testing).
Frequently Asked Questions
What is the Magnetic Transistor?
The Magnetic Transistor is a FluxWorx architecture designed to use a small control input to modulate magnetic reluctance in real time. Like a silicon transistor steers electron flow, it aims to steer magnetic flux paths on demand for motors, transformers, and power electronics.
What is active reluctance modulation?
Active reluctance modulation changes the magnetic resistance of a flux path dynamically, rather than relying on fixed geometry. FluxWorx uses this approach to reshape flux density, reduce losses, and improve control in electromagnetic systems.
What is Differential Flux Steering (DFS)?
Differential Flux Steering (DFS) is FluxWorx's method of actively biasing selected regions of a coupled magnetic structure to change effective reluctance distribution and guide magnetic operating conditions toward the desired working region.
How is FluxWorx technology different from traditional magnetics?
Traditional magnetic components rely on passive, fixed geometry. FluxWorx moves from passive magnetics to active magnetic control, enabling real-time flux steering, waveform shaping, and surge clamping through control rather than added material.
What applications can FluxWorx magnetic control technology enable?
FluxWorx technology targets switch reluctance motors, data-centre power supplies, grid infrastructure, robotics actuators, and resilient magnetic computing. Applications include smoother motor operation, soft switching, DC fault protection, and dematerialized power system design.
