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...

General Physics 2 w/o calc
Now suppose that the battery is removed and replaced with an ammeter. No current will flow through the wire because there is no energy source. Consider what will happen when a barmagnet is pushed toward the coil as shown in the figure below. When the coil "feels" the changing magnetic field caused by the approach of the bar magnet, it will thereby become energized; a current will begin to flow through it, and the ammeter will register that current. This...
