Force

Question:

A very long straight wire carries a 12-A current eastward and a second very long straight wire carries a 14-A current westward. The wires are parallel to each otherand are 42 cm apart. Calculate the force on a 6.4 m length of one of the wires. (µ0 = 4p × 10-7 T · m/A)
Answer
5.1 × 10-6 N
8.0 × 10-5 N
2.2 × 10-4 N
8.0 × 10-7 N
5.1 × 10-4 N

Answers

Use the equation for magnetic force between current carrying wires to find the solution as shown below. The force will be repulsive because the currents are opposite to each other in both the wires.Fa Mobile Leaf 12AX(244) (6 4 m) = 5:12x10-4 N zîd (0.42m) currents are opposite Force will be repulsive because in direction
