Homework Help: physics help please

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 痠, 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.
