A patient with a pacemaker is mistakenly being scanned for an MRI image. A 8.5 cm long section of pacemaker wire moves at a speed of 11 cm/s perpendicular to the MRI unit’s magnetic field and a 18 mV Hall voltage is induced.

ε = 18 mV
v = 11 cm/s
l = 8.5 cm

What is the magnetic field strength of the MRI in T?
