Question
(b) minimum Your Teaci Sodium ions (Na) move at 0.849 m/s through a bloodstream in the arm of a person standing near a large magnet. The magnetic flield has a strength of 0.256 T and makes an angle of o o. with the m tion of the s dumions. The arm contains 90.0 cm3 of blood with 2.0x1020 Na+ ions per cubic centimeter. If no other ions were present in the arm, what would be the magnetic force on the arm? My Notes O Ask Your to a uniform, magnetic field at 2.0 x 107 m/s and exhibits an of 2.0 x 1013 m/s? in the + when its velocity is in the +z-Explanation / Answer
4] Magnetic force = n* q v B sin theta where n= total number of ions
= (2e20*90)*1.6e-19*0.849*0.256* sin 50 degree
= 479.5 N answer
