Tri-Axial Square Helmholtz Coils System to Generate Uniform Magnetic Field Volume
This poster presents analysis and validation of a tri-axial square Helmholtz coils system (see Figure 1), commonly used to generate highly uniform magnetic field on a specific volume. The analysis of square Helmholtz coil is based on the Bio-Savart law [1] for which it performs a Taylor series approximation for the magnetic field at a point on the axis of symmetry, finding an approximate expres...
متن کاملNumerical Simulation of Blood Flow Mixed with Magnetic Nanoparticles under the Influence of AC and DC Magnetic Field
Nanoparticles combined with magnetic fields are one of the most important research areas in the field of biomedical engineering. Direct Current (DC) magnetic and Alternative Current (AC) magnetic fields are often used for controlling nanoparticles. It is also used for hyperthermia treatment. The purpose of the current study is to investigate the effect of DC and AC magnetic field on nanoparticl...
متن کاملMagnetic Field Stabilization for Magnetically Shielded Volumes by External Field Coils
For highly sensitive magnetic measurements, e.g., a measurement of the neutron electric dipole moment (EDM), the magnetic field has to be stable in time on a level below picoTesla. One of several measures we employ to achieve this uses an external field coil system which can stabilize the ambient external field at a predefined value. Here we report on the construction and characterization of su...
متن کاملMEMS Helmholtz coils for magnetic resonance imaging
Miniature coils for magnetic resonance imaging and spectroscopy are demonstrated. A rectangular Helmholtz arrangement based on a pair of substrates separated by spherical alignment spacers is investigated. An optimal geometry is developed using simple theory and verified by numerical analysis. Prototypes are fabricated using silicon substrates shaped by anisotropic etching to form a trough to h...
