In the case of the straight current carrying wire, if we know the direction of current, we can find the direction of themagnetic fieldusing Maxwell’s right hand thumb rule. This rule can be applied for finding the direction ofmagnetic fieldof this current carrying loop as well. Maxwell’s...
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 Flux Equation Motional EMF Lenz's Law Equation Lesson Summary Frequently Asked Questions How is Lenz's law used? When a current is induced by a magnetic field, Lenz's law is used to predict the direction of the flow of the induced current. What is the equation to calculate motio...

1 the initial magnetization curve and hysteresis loop of ferromagnetic substance The origin of the graph. The ferromagnetic substance is in a magnetic neutral state before magnetization, that is, B = H = O. When the external magnetic field increases at zero, the magnetic induction intensity B ...
Therefore, the orientation of the microrobot (the direction of 𝐦m) can be expressed in terms of the TEC’s magnetic field (𝐁TECBTEC), and the magnetic force of the microrobot can, thus, be simplified as the following equation: 𝐅TEC=𝐉B(𝐱, 𝐢TEC)𝐦=𝐏F(𝐱)𝐢TEC...
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
loop currents in the magnetized specimen, and its equation is given; and the JA hysteresis model is introduced to obtain the distribution of quasi-static magnetic flux leakage field, on the basis of analyzing the relation between the distribution of a loop current on the surface of the defect ...
A general qualitative investigation is carried out on the dispersion equation for an ordinary wave moving in a plasma perpendicular tc an external magnetic field. The regularities found are illustrated by some results of a numerical solution of the dispersion equation. (auth)关键...
magnetic field of a current in a loop or coil is obtained by summing the individual partial contributions of all the segments of the circuits, taking into account the vector nature of the field. While simple mathematical expressions for the magnetic field can bederivedfor a few current ...
