An MRI technician moves his hand from a region of very low magnetic field strength into an MRI scanner's 2.00 T field with his fingers pointing in the direction of the field.
(a) Find the average emf induced in his wedding ring, given its
diameter is 2.38 cm and assuming it takes 0.275 s to move it into
the field. (Enter the magnitude only.)

(b) If the resistance of the ring is 1.00 mΩ, how much heat will be
transferred to the ring during this time?

Alright Dude, If that worked for you... don't forget to give
THUMBS UP.(that will work for me!)
Please Vote...
If I missed something feel free to leave a comment.
atleast before giving down vote.
and, Thanks for using Chegg- Smarter way to study.

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) 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...
Jose needs an MRI (magnetic resonance imaging) scan. During the exam, Jose lies in a region of a very strong 1.7-TT horizontal magnetic field pointing from Jose's waist toward his head. A medical assistant moves Jose from the scanner, reducing the magnetic field from 1.7 TT to 0.1 TT in 1.0 ss. Consequently, the B⃗B→ field through Jose's 0.30-mm by 0.40-mm chest decreases. The conductive tissue inside his body around the outer part of his chest is a loop, with...
A technician wearing a circular metal band on his wrist moves his hand into a uniform magnetic field of magnitude 3.5 T in a time of 0.14 s. If the diameter of the band is 3.5 cm and the field is at an angle of 30° 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. .0074V .0833V 2.083V .0208V
A TMS (transcranial magnetic stimulation) device creates very rapidly changing magnetic fields. The field near a typical pulsed-field machine rises from0 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. What emf is induced in the ring as the field changes? If the band is made of a gold alloy with resistivity 6.2×10−8Ω⋅m and has a cross-section area4.5 mm2...
