Question
The section of wire shown below carries a current equal to 2.0 A from a to b. The segment is in a region that has a magnetic field whose value is 1.9 T k.My No 2. 1 points Tpler 26. P.020 The section of wire shown below carries a current equal to 2.0 A from a to b. The segment is in a region that has a magnetic field whose value is 1.9 Tk. Find the total force on the wire. Show that the total force is the same as if the wire were in the form of a straight wire directly from a to b and carrying the same current. (Do this on paper. Your instructor may ask you to turn in this work.)
Explanation / Answer
Force = (IL)XB
= (2 x (0.03i^ + 0.04j^) X 1.9k^
= (0.152i^ - 0.114j^) N
= 152 mN i^ - 114 mN j^
for the straight wire from a to b the IL vector will remain same, so same will be the force
