Single-sided NMR devices can operate under conditions inaccessible to conventional NMR while featuring portability and the ability to analyze arbitrary-sized objects. In this paper, a semi-elliptic Halbach magnet array was designed and built for single-side Nuclear Magnetic Resonance (NMR). We present an easy-to-implement target field algorithm for single-side NMR magnet design based on Gram-Sc...

The mechanical rotation of a radially positioned permanent magnet Halbach array above a conducting, non-magnetic, track generates a travelling time-varying field that can inductively create suspension and propulsion forces simultaneously. This ‘Electrodynamic Wheel’(EDW) could be used to create a relatively cheap form of maglev transportation since the track would only consist of thin sheets of...

This paper describes the finite element (FE)-based design of a slotted tubular permanent magnet actuator (TPMA) used in railway vehicle active lateral secondary suspension that improves the actuator’s thrust and lowers its cogging force under thermal and geometric constraints. To consider the electromagnetic and thermal fields and the complex interactions among the design variables, design was ...

The aim of this study was to characterize the behaviour of superparamagnetic particles in magnetic drug targeting (MDT) schemes. A 3-dimensional mathematical model was developed, based on the analytical derivation of the trajectory of a magnetized particle suspended inside a fluid channel carrying laminar flow and in the vicinity of an external source of magnetic force. Semi-analytical expressi...
