Magnet therapy problem

Reference no: EM13656452

Your roommate is sold on "magnet therapy" a sham treatment using small bar magnets attached to the body. You sceptically ask your roommate how this is supposed to work. He mumbles something about the Hall Effect speeding blood flow. In reply, you estimate the Hall potential associated with typical blood parameters in the 100-G field of a bar magnet: red blood cells carrying 2-pC charge in a 12-cm/s flow through a 3.0-mm-diameter blood vessel containing 5 billion red blood cells per mL. To show that the Hall potential is negligible, you compare your estimate with the tens of mV typical of bioelectric activity. How do the two values compare?
