What is the equation to calculate motional emf? Motional EMF is an electromotive force that is generated in response to an induced current. To calculate a motional EMF, use Faraday's law for the production of an EMF, e = - dB_flux/dt where e stands for motional emf, dB_flux is the ...

The equation for the magnetic force on a particle in a magnetic separator depends on the magnetic susceptibility of the particle and fluid medium, the applied magnetic field and the magnetic field gradient. This equation, when considered in only the x-direction, may be expressed as (Oberteuffer...
force experienced by the charge moving in the field. If a particle carrying a positive charge q and moving with velocity v through a point p in a magnetic field experiences a deflecting for F then the magnetic field B at point P is defined by the equation F=qv x B ….(i) The...
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 {...
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 ...
