Question

a patient with a pacemaker is mistakenly scanned for an MRI image. a 11.5 cm long section of pacemaker wire moves at a speed of 7.5 cm/s perpendicular to the MRI units magnetic field and a 21.5 Mac hall voltage is induced. what is the magnetic field strength of he MRI in T? ommor/T ake TutorialAssignment.aspx Home 1 Student: dalton.summers@okstate.ed Help Pro Lecture Quiz 14 TA .

Explanation / Answer

induced emf e = B*v*l*sintheta

B = magnetic field

v = speed of the wire = 7.5 cm/s = 0.075 m/s

l = length of the wire = 11.5 cm = 0.115 m

theta = angle between B and v = 90 degrees

21.5*10^-3 = B*0.075*0.115*sin90

B = 2.49 T <<<<------ANSWER
