In Equation [1], is thepermeabilityof the medium (material) where we are measuring the fields. The magnetic flux density is measured in Webers per square meter [Wb/m^2], which is equivalent to Teslas [T]. TheBfield is avector field, which means it has a magnitude and direction at e...

We consider the case where the large-scale magnetic field is also random and determine the density function of magnetic helicity. This function is invariant under gauge transformations of the magnetic vector potential. We study the equation for the magnetic helicity flux of a large-scale field and...
In this equation, B stands for the magnetic flux density, and the particle’s “effective” magnetic moment29 is \({\mathbf{m}}_{{\mathrm{eff}}}^{\mathrm{i}} = (\chi _{\mathrm{p}}V_{\mathrm{p}}/\mu _f){\mathbf{B}}\), where \(V_{\mathrm{p}}\) is particle volume, ...
relatively well. The rupture signals at 230 and 255cm are influenced by near-surface arranged mild reinforcement. From the actual probe–tendon distance of 6–7cm as well as the signal amplitude of 1.2A cm−1the number of broken steels can be obtained using equation[11.12]to be about 1–...

Equation (3) states that the number of hydrogen bubbles that evolve from the cathode is twice the number of the oxygen molecular that evolve from the anode and these mostly gather on the cathode surface due to the upward buoyancy force. This inhibits the movement of the hydrogen bubbles and ...
and theCoilfeature to model the two coils. TheMagnetic Fieldsinterface uses the curl element to define and represent the magnetic flux density in 3D. For example, to compute the gradient of they-component of the magnetic flux density (Byy), we use the expressiond(laginterp(2,mf.By),y)....

From the measured temperature rise with time, SAR value was calculated using the equation: $$ SAR = C_{p} \cdot \frac{\Delta T}{{\Delta t}} \cdot \frac{1}{{\varphi_{magnetic} }} $$ (3) where\(\frac{\Delta T}{\Delta t}\)is the change in temperature with time, i.e., ...
