Strong magnetic fields are used in such medical procedures as magnetic resonance imaging (MRI). Patients are always told to remove any metal jewellery before being placed in an MRI machine. Consider a patient with a navel ring that she has forgotten to remove. The ring is made of gold, and has a radius of 0.50 cm and a resistance of 1.0 mΩ. If the magnetic field inside the machine increases from 0.60 T to 6.5 T in 5.0 s, perpendicular to the plane of the ring, find the following.

(a) the current induced in the ring A

(b) the power delivered to the ring W

(c) If the navel ring was instead made of steel, what other consequences might occur?
