The research on the magnetic field began in 1269 when French scholar Petrus Peregrinus de Maricourt mapped out the magnetic field on the surface of a spherical magnet using iron needles. He noticed that the resulting field lines crossed at two points. He named these points “poles.” After th...
The projected area of the loop on the x−y plane is πρ2 with a new radius, ρ. Thus, the mean square of the radius can be written as 〈ρ2〉=〈x2〉 + 〈y2〉, which is the mean square of the distance of the orbiting electron normal to the magnetic field (z-axis) through...
superparamagnetic scaffold; composite; laser direct writing; static magnetic field; extracellular matrix mineralization Graphical Abstract1. Introduction Bone is the second most commonly transplanted tissue, preceded only by blood transfusion [1]. The cost of osteoporotic fractures is estimated to reach 77...
The refractive index of the magnetic fluid varies in response to the magnetic field, influencing the transmission spectrum as it enters the sensing structure through the gap. The sensitivity of the magnetic field strength, ranging from 0 to 12 mT [15], is measured at 24.2 pm/mT. It is ...
Magnetic moment, also known as magnetic dipole moment, is the measure of the object's tendency to align with a magnetic field. The objects have a tendency to place themselves in such a way that the magnetic moment vector becomes parallel to the magnetic
Moreover, the rather large HC is indicative of a hard magnetic phase. Although CFO with (111) growth orientation exhibits a relatively weak magnetic anisotropy than (100), the comparison between M-H curves under OOP and IP magnetic field at room temperature evidences an OOP magnetic easy axis...
magnetic field, with the results shown in Fig.2a. The measured nonlocal voltage signal displays a rectangular hysteresis loop in response to the applied magnetic field. At a fixedMdirection (andB = 0), the polarity of this hysteresis loop reverses when flipping the direction of the ...
11.1.3 of Griffith's "Introduction to Electrodynamics 4Ed" appears magnetic dipole radiation, which results in the equation above. According to the resultant equation, there is no magnetic field in the axis of the wire loop because theta=0. However, I think the magnetic flux density is at....
Again, the field strength and direction at any point around the bar magnet is a vector sum of the force field contributed by each of the monopole (N or S). When we examine equation (1) in terms of unit of measurement, we see that the magnetic force, Fm retains its fundamental unit ...
A case of particular interest is the one where the material is subject to a cyclic field of frequency f, with the field and the average magnetic induction B in the material remaining co-linear during the process. Then the time integral [1]W=?HdBdtdt over one magnetization cycle gives the...
