Induced Voltage

  1. Nov 6, 2008 #1
    OK, so we have a stick 91cm long which is accelerated by 1m/s/s in a magnetic field B= 0.606T.

    I need to find the induced voltage at time t = 288ms.

    So U = B/V which is B/(a*t)

    When i calculate i get 2 Volts which i think is too much. Plus the solution should be given in mV. Is this the correct result or I'm doing something wrong?

    Uh, that equation is wrong. For one thing, it says a motionless stick (V=0) would generate an infinite amount of EMF!

    What is the equation for EMF or U in terms of area and magnetic field?

    Oh, sorry it's B * L * V, i missinterpreted l and /. Tnx, anyway it is a stupid equation the way i wrote it, I should have seen that.

    No problem. If you're still stuck post again, but it sounds like you have it now.
