a) A metal ring of 2.40 cm diameter moves into the magnetic field of an MRI scanner in 0.30 s from where the magnetic field is zero. The magnetic field in the MRI is 1.90 T and the plane of the ring is perpendicular to this field. Determine the voltage induced in the ring. b) If the ring in the problem above has a resistance of 0.009 Ω, what is the current induced in the ring, and in what direction...

A technician wearing a circular metal band on his wrist moves his hand (from a region where the magnetic field is zero) into a uniform magnetic field of magnitude 1.8 T in a time of 0.20 s. If the diameter of the band is 7.0 cm and the field is at an angle of 45° with the plane of the metal band while the hand is in the field, find the magnitude of the average emf induced in the band....

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 2.3-cm-diameter wedding band is parallel to the field. PART A: What emf is induced in the ring as the field changes? PART B: If the band is made of a gold alloy with resistivity 6.2×10-8 Ω⋅m...
