Problem 33 Easy Difficulty

Considerable scientific work is currently under way to determine whether weak oscillating magnetic fields such as those found near outdoor electric power lines can affect human health. One study indicated that a magnetic field of magnitude $1.0 \times 10^{-3} \mathrm{T}$ , oscillating at $60 . \mathrm{Hz}$ , might stimulate red blood cells to become cancerous. If the diameter of a red blood cell is 8.0$\mu \mathrm{mm}$ , determine the maximum emf that can be generated around the perimeter of the cell.

Answer

1.9 \times 10^{-11} V

Okay, so, uh, the maxim of the math generated will be cool to number turns in the coil times. Magnetic seals. Frank, He plans bury our times. Angular frequency omega. So this is equal to two pi times. The frequency indicated, uh, and is one in this case. So we have be a times to pay off its flag. Those values in he is 10 to the negative. You Tesla A is high times r squared. Ours of micro is for my confidence. So four times 10 to the negative six meters where you square and that's most played by two pi times 60 hertz Did you induced BMS off? Just about 1.9 times 10 to the negative 11 volts, which is really, really low. And that's goodness for human health.
