4c), but leads to high intensity fringes around the metallic hardware in high-field MR images due to incorrect spin mapping (see Fig. 4d, taken at 3 T). These effects depend supralinearly on the magnetic field strength and are barely perceptible at fields \(<0.1\) T28. The field ...

The solenoid field consists of two components: a dominant, axial component, with a maximum strength at the center of the solenoid, and a weak, radial component with relevant effects only towards the ends of the solenoid. Charged particles moving outside the magnetic axis are azimuthally ...
In both EPR and NMR, the signal intensity depends on the Boltzmann distribution of spin states according to Eq. (1). $$\begin{array}{*{20}c} {\frac{{N_{{{\text{High}}} }}{{N_{{{\text{Low}}} }} = e^{{\left( {\frac{{ - \gamma \hbar B_{0} }}{2\pi kT}} \right...
Each of the solenoid coils is supplied with correcting currents from current sources 24-29 via lead out wires independently. If each of solenoid coil currents is changed while keeping the ratio between them, intensity of a first-order axis-inclined magnetic field can be modified. With the ...

where \({\mu }_{0}\) is the vacuum relative permeability, H (A/m) is the magnetic field intensity to be measured, \({d}_{n}\) is the differential surface element that is perpendicular to the loop, which is used to calculate the flux of the magnetic field through the unit-cell,...
The intensity of the magnetic wave strongly depends on magnetic permeability (μ). Almost all media including air, water, wood and even metals such as gold (Au) and aluminum (Al) have a similar relative magnetic permeability (μr≈ 1). Therefore, a signal or power transmission based on ...
