A TMS (transcranial magnetic stimulation) device creates very rapidly changing magnetic fields. The field near a typical pulsed-field machine rises from 0 T to 2.5 T in 200 μs. Suppose a technician holds his hand near the device so that the axis of his 1.9-cm-diameter wedding band is parallel to the field.
(A) What emf is induced in the ring as the field changes?
Express your answer to two significant figures and include the appropriate units.
(B) If the band is gold with a cross-section area of 4.0 mm^2, what is the induced current? Assume the band is of jeweler's gold and its resistivity is 13.2 x 10^10 Ω*m.
Express your answer to two significant figures and include the appropriate units.

Electroplating is a way to coat a complex metal object with a very thin (and hence inexpensive) layer of a precious metal, such as silver or gold. in essence the metal object is made the cathode of an electrolytic cell in which the precious metal cations are dissolved in aqueous solution. suppose a current of 480.ma is passed through an electroplating cell with an aqueous solution of agno3 in the cathode compartment for 46.0 seconds. calculate the mass of pure silver deposited on a metal object made into the cathode of the cell. round your answer to 3 significant digits. also, be sure your answer contains a unit symbol. ×10μ
