Part A : 4.33 Volt.
Part B : 4764 Amperes.
Given Data :
Field near a typical pulsed-field machine rises from 0 T to 2.5 T in 200 μs.
Axis of his 2.1-cm-diameter wedding band is parallel to the field.
Part A :
induced emf = rate of change of magnetic flux
= d (B A )/dt
= A dB/dt
= { π (2.1 x 10^-2 / 2)^2) (2.5) } / (200 x 10^-6)
E = 4.33 Volt
Part B :
R = rho L / A
R = { (6.2 x 10^-8) ( π x 0.021) } / (4.5 x 10^-6)
R = 9.10 x 10^-4 Ohm
We know, (I = V/ R)
I = 4.33 Volts / 9.10 x 10^-4 Ohm
I = 4764 Amperes
What exactly is the function of TMS?
Transcranial magnetic stimulation (TMS) is a noninvasive procedure that uses magnetic fields to stimulate nerve cells in the brain to alleviate depression symptoms. TMS is usually used when other depression treatments have failed.

➤ Although your question isn't complete, I may have assumed that you were referring to this specific question.
The complete question is :
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 2.1-cm-diameter wedding band is parallel to the field.
Part A: What emf is induced in the ring as the field changes? Express your answer to two significant figure E= ___ unit_
Part B: If the band is made of a gold alloy with resistivity 6.2×10−8Ω⋅m and has a cross-section area 4.5 mm2 , what is the induced current? Express your answer to two significant figures and include the appropriate units. I= ___ units__
