The rest of the conducting bodies are free from the EM field. Using Maxwell's equations in quasi-static approximation, where the displacement current is neglected [68] in the formulation of the magnetic vector
Figure 1. (a) The magnetic field produced by a long straight conductor is perpendicular to a parallel conductor, as indicated by RHR-2. (b) A view from above of the two wires shown in (a), with one magnetic field line shown for each wire. RHR-1 shows that the force between the pa...
The film thickness in the write head is typically 2–3 μm and the air gap between the head and medium is of order 100 nm for high density recording. A read head, on the other hand, operates from its quiescent or demagnetized state. A read head should respond to the fringe field of...
Magnetic field effects on electrocatalysis have recently gained attention due to the substantial enhancement of the oxygen evolution reaction (OER) on ferromagnetic catalysts. When detecting an enhanced catalytic activity, the effect of magnetic fields on mass transport must be assessed. In this study,...

To that end, ordinary transmission lines utilize two parallel electric wires of very high conductivity. Very recently, ...
This suggests that the nucleation of martensite was more difficult in the presence of magnetic field. The CC slope of the SHT NiCoMnIn single crystal was measured and shown in Fig. 3c to be 2.2 MPa K−1. Per the Clausius-Clapeyron equation mentioned above, VS-FR loading generated...
After removing constants from the equation for the force on a wire in a magnetic field we can write F1∝l1sin(75) F2∝l2sin(90) The length of each wire exposed to the magnetic field is not the same so the length...
The magnetoresistance (MR) is usually defined by Equation 1, therefore, for manganites it is negative, because the resistivity decreases with applied magnetic field. Figure 3 presents typical characteristics of one of the mostly investigated lanthanum manganite La1−xSrxMnO3 crystals with different ...
Step 1: Connect the battery, wires and switch in a complete loop (a complete circuit). Move the switch to the 'off' position. Step 2: Position the wire so that is moves between the poles of the magnet. It should be pointing at 90 degrees to a line between the poles. Data...
In particular, the stray field created by the long NWs enhances the magnetostatic interactions between wires; whereas the empty inner core of the NTs favor local interactions within each tube (Proenca et al., 2013b,c). Therefore, for the larger diameters presented in Figure 24.16, one can ...
