    Your right; you can get the same solution both ways,

    Magnetic flux through loop inside of solenoid

    Wrong equation, never mind. induced emf = -L * dI/dt L= flux / I

    Magnetic flux through loop inside of solenoid

    Thanks that worked; I tried that before, but used the diameter instead radius. woops Part B is giving me trouble as well. induced emf = -NA * dB/dt =-1800*(.025)^2 * pi * (-4/3)

    Magnetic flux through smaller coil within solenoid

    Homework Statement A solenoid has 235 turns of wire wrapped along its length of 27 cm. The diameter of the solenoid is 1.5 cm. In the middle of the solenoid is a smaller coil of diameter 1.0 cm with 50 turns of wire along its 2.0 cm length. The two coils are coaxial. A current of 15 A is in...

    Magnetic flux through loop inside of solenoid

    So to find the flux through the smaller loop do you first find the flux through the solenoid using its area and then somehow use the smaller loop's area to find its flux?
