    [Electric Power] Solenoid, finding Flux

    The answer says it's 0 but I don't understand which direction is the magnetic field.

    Re: [Electric Power] Solenoid, finding Flux

    Use the Equations:
    1) Magnetic Flux= Area of Loops x B x ( Magnetic Field).
    2) Magnetic Flux= Area Loops x B x cos (\theta)

    Since the magnetic field is perpendicular to the plane of loops, no a, so use equation 1 *Dont forget to convert cm^2  to  m^2

     (\frac{8 * 10}{10,000})  (5 X 10^-2)

    MF = 0.0004 volts/sec
