The magnetic flux through a coil of wire changes from 8 Txm ^2 to zero in a time 0.5 s. what is the magnitude of the average voltage induced in the coil during this change?
please explain your answer..

  • physics help -

    Induced voltage is the rate of change of magnetic flux. That is Faraday's law.

    Divide the flux change in T*m^2 units by the time in seconds and you will get the average induced voltage during the change
