Assume there is a current of 3.0 A traveling clockwise in a loop around this piece of paper (which is approximately 22 cm wide and 28 cm long).There is an infinitely long wire that runs parallel to the top edge of the paper that carries a current of 5.0 A.If the distance between the top edge and the wire is 50 cm find the magnitude of the force between the wire and the loop. A)zero B)1.3 * 10^-7 N C)4.7 * 10^-7 N D)2.2 * 10^-6 N

The force between the wire and the loop can be calculated using the formula F = μ₀IL/d, where μ₀ is the permeability of free space, I is the current, L is the length of the wire, and d is the distance between the wire and the loop. In this case, we have:
F = (4π×10⁻⁷ T·m/A)(5.0 A)(22 cm)/(0.5 m) = 4.7×10⁻⁷ N
The direction of the force is given by the right-hand rule, which indicates that it is perpendicular to both the wire and the loop, and is pointing into the page. Therefore, the correct answer is C.
