The Earth's Magnetic Field
The Earth's magnetic field is essential for life on Earth, as we know it, to exist. It forms a magnetic shield around the planet, protecting it from high energy particles and radiation from the Sun, which can cause damage to life, power systems, orbiting satellites, astronauts and spacecrafts. This …

Tilt-Compensated Magnetic Field Sensor
… the accuracy, reliability, and response of magnetic detection systems. Perturbations in the magnetic field reading resulting from motion cause degradation of the output signal, compromising the performance and reliability of the magnetometer system. The purpose of this document is to …

Electromagnetic stirring using a travelling magnetic field
Electromagnetic stirring of liquid metal is widely used during continuous casting in iron and steel industries to improve the quality of the products. In this thesis we aim to develop a theory for traveling linear stirrers in closed channels. We consider a channel filled with an incompressible, …

Modeling of magnetic field driven simultaneous assembly
The Magnetic Field Driven Simultaneous Assembly (MFDSA) is a method that offers a non-statistical and deterministic solution to the problem of assembly via batch processing; a hybrid of serial and parallel processing. The technique requires the use of electromagnets as well as soft and hard …

Plasma stability in a dipole magnetic field
… axially symmetric plasma, confined by a poloidal magnetic field with closed lines, is considered. In such a system the stabilizing effects of plasma compression and magnetic field compression counteract the unfavorable field line curvature and can stabilize pressure gradient driven …

Enhanced Navigation Using Aerial Magnetic Field Mapping
… applies the methods of previous work in aerial magnetic field mapping and use in state estimation to the Virginia Tech Swing Space motion capture indoor facility. State estimation with magnetic field data acquired from a quadrotor is comparatively performed with Gaussian process regression, a …

The Magnetic Field of Protostar-Disk-Outflow Systems
… of protostellar cores reveal complex magnetic field configurations that are distorted in the innermost disk region. Unlike the prestellar phase, where the magnetic field geometry is simpler with an hourglass configuration, magnetic fields in the protostellar phase are sculpted by the …

PARALLEL ELECTRIC FIELD ON AURORAL MAGNETIC FIELD LINES
The interaction of Birkeland (magnetic-field-aligned) current carriers and the Earth's magnetic field results in electrostatic potential drops along magnetic field lines. The statistical distributions of the field-aligned potential difference (phi)(,(PARLL)) were determined from the energy spectra …

Quantised charge pumping in a perpendicular magnetic field
… electron pump in the presence of a perpendicular magnetic field are documented in detail in this thesis. Perhaps the most important observation is an enhancement of the quantisation as a result of the applied field. To determine the accuracy of the quantisation we applied novel measurement …

Magnetic-field-induced antiferromagnetism in the Kondo lattice
… useful model of a Kondo insulator in an applied magnetic field. A variational mean field analysis of this system on a square lattice, backed up by quantum Monte Carlo calculations, reveals an interesting separation of magnetic field scales. For Zeeman energy comparable to the Kondo energy, the …

Investigation of Magnetic Field Profile Effects in Hall Thrusters
… study was to show the relationship of different magnetic field profiles to the acceleration region length of a Hall thruster. The general transport equations were simplified and solved using a one-dimensional analysis. Some of the model assumptions include quasineutrality, Maxwellian electrons, …

Road vehicle recognition and classification using magnetic field measurement
… approach uses a roadside-installed, low-cost magnetic sensor and associated data collection system. The system measures magnetic field changes to count, detect, and classify passing vehicles into a number of vehicle types. We compare each vehicle using dynamic time warping (DTW), then extend …
