A princess refuses to remove her metal tiara as she has a MRI done, and is moved into a 3.50T field with her head point directly into the field.

a. Find the average emf induced in the 20cm diameter tiara, the current induced, the power dissipated, and the magnetic field induced if it takes 3s for her to move into the field and the tiara has 0.020Ω of resistance.

b. How would the direction of the induced field compare going in and going out?

    A patient is having a magnetic resonance imaging scan (an MRI) and has neglected to remove a 8.1 cm diameter metallic bracelet. The resistance of the bracelet is 0.0110 Ω. The magnetic field within the MRI's solenoid is perpendicular to the opening of her bracelet. While taking the scan, the magnetic field decreases from 1.05 T to 0.35 T in 1.50 seconds. What is the magnitude of the average induced voltage in the bracelet?
