We can observe that the magnetic field lines are in the form of concentric circles near the sides of the loop but towards the centre of the loop, the magnetic field lines become almost parallel which indicates that this part of the coil has a uniformmagnetic field. In other words, we can...
Wire magnetic field In the case of an electric current passing through a loop, the magnitude of magnetic field equation at the loop center is: {eq}B=\frac {\mu _{0}*I}{2*R} {/eq}, where R here is the loop radius measured in meters (m).The...

magnetic anisotropy and a fictitious field (Nagendran et al., 2007); as another example, in material with nonzero magnetostriction, magnetization can be introduced on the cutting edge of the sample (Hur et al., 2002), owing to the influence of residual stress on magnetic moments and domains...
A difficult problem concerns the determination of magnetic field components within an experimentally inaccessible region when direct field measurements are not feasible. In this paper, we propose a new method of accessing magnetic field components using
Coiling wire increases magnetic field. The wire loop in Figure 3.23 is actually just an inductor. In most instances the wire will be wound around some type of ferromagnetic material, such as iron but there are also inductors made that have no material in the center. These inductors are ...
The PTCDA molecule (white, hydrogen; grey, carbon; red, oxygen) is attached in standing configuration to an STM tip, consisting of Ag (light blue) and Fe (orange) atoms. The Fe atoms provide spin polarization. In a \({\vec{B}}\) field (in-plane B|| and out-of-plane B⊥ ...
Fig. 1-7. Larmor procession of an electron orbit about a magnetic field H = uoB. Thus, Equation 1-54 can be written as (1-56)dLdt=−L→×qB→2m=−L×ωp where ωp is ωp=qB2m which is known as the Larmor frequency. Theoretically, the magnetic dipole does not tend to align...
A sensor positioned on the inside (magnet side) of the pipe is typically used to measure the magnetic field adjacent to the pipe wall. At a metal-loss anomaly, the sensor records a higher flux density or magnetic field, which indicates the presence of an anomaly. In this manner, an MFL...
