BACKGROUND Effects of electromagnetic fields on healing have been investigated for centuries.

Introduction Micro Helmholtz coils are needed in medical technology for high-resolution magnetic resonance imaging (MRI) or for nuclear magnetic resonance (NMR) spectroscopy at the micro level. The coil sensitivity, and therefore the desired signal, is maximized when the size of the coil matches that of the sample [1, 2]. Small sample analysis with micro Helmholtz coils shows exceptional perfor...

Atomic magnetometers have found widespread applications in precise measurement of the Earth’s magnetic field due to their high sensitivity. In these measurements, various methods have been utilized to compensate the Earth’s magnetic field in an unshielded environment. In this paper, we have proposed a method based on finding the minimum resonance frequency (corresponding to minimum magnetic fie...

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...

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...

This paper provides an optimal parametric design for tri-axial nested Helmholtz coils, which are used to generate a uniform magnetic field with controllable magnitude and direction. Circular and square coils, both with square cross section, are considered. Practical considerations such as wire selection, wire-wrapping efficiency, wire bending radius, choice of power supply, and inductance and t...

1. PURPOSE AND DESCRIPTION The narrow beam tube 06950.00 is used in conjunction with the pair of Helmholtz coils 06960.00 to study the behaviour of an electron beam in a magnetic field normal to the electron trajectory, which is made visible by the fluorescence of the insert gas with which the tube is filled. The tube has an axial scale shaped like a ladder, whose metal 'rungs' are given a coat...
