UCF PHY2054 Post Lab-Unit 09FlEx and Faraday's Law1. A magnetic field has a magnitude of 0.078 T and is uniform over a circular surface whose radius is0.10 m. The field is oriented at an angle of o= 25° with respect to the normal to the surface. What isthe magnetic flux through the surface?2. Magnetic Resonance Imaging (MRI) is a medical technique for producing pictures of the interior ofthe body. The patient is placed within a strong magnetic field. One safety concern is what wouldhappen to the positively and negatively charged particles in the body fluids if an equipment failurecaused the magnetic field to be shut off suddenly. An induced emf could cause these particles to flow,producing an electric current within the body. Suppose the largest surface of the body through whichflux passes has an area of 0.032 m and a normal that is parallel to a magnetic field of 1.5 T.Determine the smallest time period during which the field can be allowed to vanish if the magnitudeof the average induced emf is to be kept less than 0.010 V.
