Scientific work is currently underway to determine whether weak oscillating magnetic fields can affect human health. For example, one study found that drivers of trans had a higher incidence of blood cancer than other railway workers, possibly due to long exposure to mechanical devices in the train engine cab. Consider a magnetic field of magnitude 0.00100 oscillating sinusoidally at 51.0 Hz. If the diameter of a red blood cell is 7.80 m, determine the maximum em that can be generated around the perimeter of a cell in this field
The figure below shows an end view of a single-turn square loop of metal wire in the center of and coaxial with a very long solenoid with a circular cross section. The solenoid is 19.0 cm long, has a radius r = 3.00 cm, and consists of 104 turns of wire. The length of each side of the square loop is l = 1.50 cm. (a) The current in the solenoid is 4.00 A. What is the magnetic flux through the square loop (in T.m?)? T m² (b) The current decreases from 4.00 A to zero in 2.00 s. What is the magnitude of the average induced emf in the square loop (in V) over this time?
