If a wire with a currentiis placed in an external magnetic fieldB, how will the force on the wire depend on the orientation of the wire? Since a current represents a movement of charges in the wire, the Lorentz force given in equation (5) acts on the moving charges. Because these ch...
In the article, we derive the equation governing the current helicity evolution. It is shown that the joint effect of the differential rotation and magnetic fluctuations in the stratified media can be responsible for the generation, maintenance and redistribution of the current helicity. The ...
As an example, the current and coil force are worked out for the uniform field magnet formed by intersecting parallel cylindrical conductors and compared with prior results.关键词: integral equations magnetic field measurement/ A0755 Magnetic instruments and techniques ...

But the charge per unit time is the current, q/t = I, so we have I=nev and the force on the wire becomes (12-4)FM=BIL (v⊥B) Equation 12-4 is correct if the direction of the wire is perpendicular to the field direction. In the event ...
Two types of magnet-related forces can cause injury in a patient with a bio-implant: (a) an attractive transitional force that is proportional to B0, gradient field strength, and the mass, shape and magnetic susceptibility of the object, and (b) the torque that attempts to align or rotate...
You will also learn about the solenoid magnetic field equation. What is a solenoid? If we run a current through a wire, there is a magnetic field around it. A solenoid is a wire wound tightly in a long, thin coil. Due to its shape, if we run current through the solenoid, there ...

The amount of charge which flows through any conductor per unit time is known as current and we can express it by $I = \dfrac{q}{t} = \dfrac{{2e}}{t}$ Substituting the values in above equation, We will get, $I = \dfrac{{3.2 \times {{10}^{ - 19}}}{2} = 1.6 \times {...
