Considerable scientific work is currently underway to determine whether weak oscillating magnetic fields such as those found near outdoor power lines can affect human health. One study indicated that a magnetic field of magnitude 1.0 10-3 T, oscillating at 60 Hz, might stimluate red blood cells to become cancerous. If the diameter of a red blood cell is 8.5 µm, determine the maximum emf that can be generated around the perimeter of the cell if the magnetic field strength is 1.3 10-3 T.

So the flux is B*area
Assume B is 1.3E-3 sinwt where w is 2PI*60.
Take the derivative of B, then d flux/dt is equal to Area * the derivative of B.
