Practice covered

  1. Magnetic flux Phi_B through a loop of area A in magnetic field vecB is defined as:
  2. A circular loop of radius 0.10 m has its plane perpendicular to a 0.50 T magnetic field. Calculate the magnetic flux (in webers) through the loop. (Use pi approx 3.14)
  3. Faraday's Law states that the induced EMF in a loop is:
  4. The magnetic flux through a coil decreases from 0.60 Wb to 0.20 Wb in 0.10 s. Calculate the magnitude of the induced EMF (in volts).
  5. Lenz's Law states that the direction of induced current is such that:
