Sodium ions (Na+) move at 0.853 m/s through a bloodstream in the arm of a person standing near a large magnet. The magnetic field has strength of 0.258 T and makes an angle of 53.0 degree with the motion of the sodium ions. The arm contains 80.0 cm3 of blood with a concentration of 4.00 x 1020 Na+ ions per cubic centimeter. If no other ions were present in the arm, find what would be the magnetic force on the arm? (Answer in N)
