Discuss the possibility that a Hall voltage would be generated on the moving heart of a patient during MRI imaging. Also discuss the same effect on the wires of a pacemaker. (The fact that patients with pacemakers are not given MRIs is significant.)

Please help me fast sir
In the arrangement shown, a conducting bar of negligible resistance slides along horizontal, parallel, friction-less conducting rails connected as shown to a 4 ohm resistor (use this value. Ignore the 2.0 ohm mentioned in the figure for the resistance). A uniform 1.7-T magnetic field is perpendicular to the plane of the paper. If L = 51 cm, at what rate is thermal energy being generated in the resistor at the instant the speed of the bar is equal to 4.8 m/s? 2.02 L.
If possible i'd like a detailed solution for this question, with the name of equations used to solve and a bit of an explanation, thank you
