Na+ (Sodium ions) moves at 0.841 m/s via a bloodstream in the arm of a person standing close to a large magnet. The magnetic field has strength of 0.253 T and makes an angle of 47.0° with the motion of the sodium ions. The arm includes 90.0 cm3 of blood with a concentration of 3.00 x1020 Na+ ions per cubic centimeter. If no other ions were there in the arm, then what would be the magnetic force on the arm?
