4. [-/10 Points] DETAILS SERCP7 19.P.010.SOLN. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER Sodium ions (Na* ) move at 0.841 m/s through a bloodstream in the arm of a person standing near a large magnet. The magnetic field has a strength of 0.254 T and makes an angle of 48.09 with the motion of the sodium ions. The arm contains 85.0 cm of blood with 2.50 x 1020 Na* lons per cubic centimeter. If no other ions were present in the arm, what would be the magnetic force on the arm
