As the flux is alternating, there will be clearly a rate of change in flux linkage with respect to time in another coil. Flux linkage is defined as where is the voltage across the device or the potential difference between the two terminals. The unit of inductance is the Henry. I was originally under the impression that flux cutting was when there was relative motion between a conductor and a magnet and linking was when there was a change in the magnetic flux density. Where the surface S is a planar surface with area A, and the magnetic field is constant with magnitude B, a simplified version of the formula can be used: Φ=B. (i) Coil A is held in a very strong magnetic field and coil B is held in a weak magnetic field.

Magnetic flux density is inversely proportional to the distance from a current-carrying conductor, as measured in a plane perpendicular to the conductor. This is the product of the flux Φ and the number of coils in the wire N. I'm slightly confused here because earlier on the page it defines "flux linkage" as the total flux times the number of turns on a solenoid (so "flux linking" and "flux linkage" are different?), and in another book it defines "flux linking" as when magnetic field lines pass through an area (e. The magnetic flux (φ) through a surface is given by; where B is the magnetic field passing through the surface, A is the area of the surface, and θ is the angle between the magnetic field and the normal to the surface.

So over long distances of conductor in transmission systems they store a component of flux in themselves. The flux linkage, magnetic coenergy and static torque are cal- culated fordifferent rotorpositions and statorcurrents. The greater the concentration, the stronger the field. If you put your loop in the lines here, the high magnetic flux density, multiplied by the area of your loop , gives you lots of magnetic flux that 'links' your loop. the cross-section of a coil) so the area is "linked" by the flux. so flux linkage isnt a real thing like flux is of a magnetic field, rather it is value whose change over time, will tell you how much Emf is induced across a whole coil? Or is it just the fact that E= - dNΦ /dt hence even if it were only the flux Φ changing, you would say change in flux linkage induces not change in flux?. No physical memristor component has yet been demonstrated. Thread starter wes; Start date Oct 31, 2011; Search Forums; New Posts; Thread Starter. Electricity A measure of the induced voltage in a circuit caused by a magnetic flux and equal to the flux times the number of turns in the coil that surrounds it.
