I am interested in finding out if there is an equation that you can use to calculate the amount of 'current or voltage' produced in a single copper wire by knowing the 'strength' and 'speed' of a moving permanent magnetic field that is perpendicular to said wire. Application is that 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,...
Different change of the magnetic field between these two points can be obtained by using Eqs. (6) and (9), Figure 4 (a) The location of the magnetic dipole of \(\overrightarrow{\mathrm{m}}\) relative to the atomic magnetometer. (b) Moving and mapped mesh for stationary and linearly...
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 potential the Laplace equation in a nonconducting space is (7.14)ΔA=0. Assuming ...
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...
Magnetic Force Equation The Lorentz force law relates magnetic field to the force felt by a moving charge or current. This law can be expressed as a vector cross product: \boldF=q\boldv×\boldB for a charge q moving with velocity v in magnetic field B. The magnit...

The magnetic induction, B, field intensity, H, and magnetization, M, are related by the equation: (13.1)B=μ0(H+M) where μ0 is the permeability of free space and has the value of 4π×10−7 N A−2. In a vacuum, M=0, and M is extremely low in air and water, such ...
such as non-orthogonal SHE for realizing field-free current-induced perpendicular magnetization reversal34. Moreover, strong interaction between the two constituting materials, despite the existence of a vdW gap region, can lead to coherent distribution of active electronic states across the vdW interfac...
