    Current Equation from Magnetic Field

    You cannot heat up a PM with an rapidly changing opposing magnetic field can you?

    Current Equation from Magnetic Field

    Yes, throw all heating constraints out the window. From what I took in school, there is something known as "Regulation Up" characteristic. At a SET PF, with increasing load and current, eventually the 'terminal voltage' begins to decrease. This happens even at unity PF. I am curious as to WHY...

    Current Equation from Magnetic Field

    What I am interested in is, ultimatley how to calculate how much current a given 'SET' voltage can put out from a permanent magnet generator, assuming ideal situation with superconducting wires, and unity PF. Im looking for ball park numbers/ratios/formulas.

    Current Equation from Magnetic Field

    Thanks guys, that's exactly what I was looking for. My next question is how do you determine how much current a given generator can pump out? I am aware that the load/impedance determines the current but ultimately there has to be some kind of limit.(I=V/R) Given the following values pulled...

    Current Equation from Magnetic Field

    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 a...
