Investigators are researching the appearance of a strange movement of objects in what the local community considers a haunted house. The owners of the house attribute the cause to poltergeists; others blame overly-strong magnetic fields. As a scientific investigator of paranormal claims, you decide to investigate. You will start by focusing on magnetic fields. Paranormal skeptics use other equipment to investigate claims of ghosts and poltergeists, such as video and audio recorders. Using a coil made of 321 turns of single-strand copper wire, you use a motor to rotate the coil at a constant angular speed of 60.0 rev/s at various orientations and locations throughout the room. In one particularly significant orientation, you notice a maximum induced voltage of 1.15 V appearing in the coil. If the radius of the coil is 1.00 cm, how strong was the magnetic field that produced this emf? strength of the magnetic field: 0.0028745 T

If the radius of the coil is 1.00 cm, how strong was the magnetic field that produced this emf? Strength of the magnetic field: 0.0028745 T Can you rule out the possibility that unusually strong magnetic fields are causing the strange behavior? - No, because the magnetic field producing the emf is much stronger than the magnetic field of the Earth. - Yes, because the magnetic field producing the emf is about the same strength as that of the Earth.
