18. According to Wolff's law, detailed by Julius Wolff in the late 19th Century, bones in the human body "remodel" themselves based on stresses and strains they are placed under. While the exact mechanism for this process is unknown, a piezoelectric response in which the bone develops electric charge and electric current when placed under stress is suspected. Electric stimulation by a 100 μA/cm² current has also been shown to accelerate bone repair and regeneration after a fracture. The resistivity of human bone is 170 2 m. Assume bone is an ohmic conductor. b) a) establish What is the potential difference (in V) that is needed to establish a current with density 100 μA/cm² over a 4.98 cm-long segment of the tibia, the shin bone, with a diameter of 2.70 cm? What is the magnitude of the magnetic field (in T) generated by the current in this segment at a radial distance of 10.2 cm from the center-point of the segment?
