Calculate Emf in a magnetic field

  1. Feb 13, 2012 #1
    1. The problem statement, all variables and given/known data
    Calculate the EMF induced in a 5.0 cm by 2.5 cm rectancular coil containing 150 loops if it rotates at 28 Hz in a 0.014 T magnetic field

    2. Relevant equations
    ε=-N ΔΦ/Δt

    3. The attempt at a solution
    =.05m x .025m =1.25 x 10^-3

    ε=-N ΔΦ/Δt
    =150 x (1.25x10^-3) / (1/28)? ----> i think this is where my problem is with Hz

    Thanks for the help :)

    N is 150 and you have used 250 in your equation
