Correct Answer 1-221.8 Final Grade 100% Student Answer 1-2.21 10 1-22 Grade Detail Correct Student Feedback Final Answer Credit 100% Submission History Answer -2.21 102 -22 Hints Feedback Totals 0% 0% 0% 0% Totals 0% 0% 0% 0% through a strong horseshoe magnet, subjecting 5.00 cm of it to a perpendicular 1.75 I field, what force is exerted on the segment of wire in N?Explanation / Answer
We know that Force is given by:
F = i*L*B
i = 221.8 Amp
L = 5 cm = 0.05 m
B = 1.75 T, then
F = 221.8*0.05*1.75
F = 19.4 N
