3. Brain waves generate miniscule magnetic field pulses that change from OT to 10-15T over a small amount of time, t. Electroencephalography (EEG) uses small devices that surround patients' skull to take measurements in the form of an induced emf-voltage across one loop of wire. (Note: the area of a human skull can be approximated as a sphere with a radius of 9cm.) A brain pulse is measured. It induces a voltage of 3.0 x 10-15 V, what was the time length of that brain pulse? 3.
