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...

Abstract We present a high-flux source of cold ytterbium atoms that is robust, lightweight and low-maintenance. Our apparatus delivers 1 × 10 9 s −1 into 3D magneto-optical trap without requiring water cooling or high current power supplies. achieve this by employing Zeeman slower 2D fully based on permanent magnets in Halbach configurations. This strategy minimizes mechanical complexity, stray...

Temperature degrading of magnet material is of mayor interest in many applications. Segmented rare earth Halbach arrays are subject to an augmented temperature degrading effect due to local demagnetisation. This paper presents results using a parameter-based material demagnetisation model. Measurement results of high temperature Halbach arrays are validated with 2D FEA.

Magnetic fields are a standard tool in the toolbox of every physicist, and required for characterization materials, as well polarization spins nuclear magnetic resonance or electron paramagnetic experiments. Quite often static field sufficiently large, but fixed magnitude is suitable these tasks. Here we present permanent magnet assembly that can achieve strengths up to 1.5T over an air gap len...

This document deals with the design of a Permanent Magnet Synchronous Motor (PMSM) to peripherally drive counter-rotating pump inducer. The motor/pump is associated using rim-driven principle where motor’s active parts are located at periphery inducer blades. It proposes Halbach array permanent magnets for rotor motor. solution allows generation Sinusoidal Electromotive Force (EMF). Therefore, ...

The ability to use magnets external to the body to focus therapy to deep tissue targets has remained an elusive goal in magnetic drug targeting. Researchers have hitherto been able to manipulate magnetic nanotherapeutics in vivo with nearby magnets but have remained unable to focus these therapies to targets deep within the body using magnets external to the body. One of the factors that has ma...
