What are the three ways to produce an induced emf using a magnet and coil of wire? Give an applied example of each. An AC Motor runs on a max emf of 120V but requires the motor to make 100 cycles per second. How strong must the B field in the coil be to create the optimum output voltage and frequency in the 200 turn coil? Oersted's Law states that a changing electric field (or voltage) can induce a magnetic field. Design an experiment in which a changing electric field (or voltage) creates a B field using a coil of wire and a battery. Design an experiment to utilize the constant magnetic field of the earth to create an emf.Explanation / Answer
1) Three ways to produce induced emf:
1) Changing the magnetic field
eg. Move magnet near stationary coil and vice-versa
2) Changing the area of the loop
3) Change the angle between the magnetic field and. the loop
eg. if B is perpendicular to plane of coil then rotate the. coil around the axis passing along diameter.
