Science Homework Help

One way to track a patient’s eyes in a vision experiment I have the patient wear contact lenses with tiny wire coils in them. The patient then sits in a magnetic field so that the field induces a current in the coil when the patient’s eyes move. What is the EMF induced in the lens coil when the patient shifts their eyes by 5 degrees in 0.2 seconds. The coil has 20 turns, is 6 mm in diameter, and the magnetic field is 1 T.
