| - | You have been hired by the Acme Corporation to develop a new detector for locating Road Runners (Accelleratti incredibus). A key portion of the detector has two wires that must run past each other for the length of the apparatus. However, it is important that they do not touch as that would cause an explosion, thereby harming the detector's only qualified user, Coyote (Carnivorous vulgaris). Your job is to assess the force acting on each of the wires as a result of a current passing through them. Here are the specifications: | + | You have been hired by the Acme Corporation to develop a new detector for locating Road Runners (Accelleratti incredibus).

| - | Based on the above calculations, the maximum magnetic force acting on each wire for a 4.5 A current is ___. Using the right-hand rule, or checking the signs of the calculated forces, you'll find that the wires attract each other when the current goes in the same direction, and the wires will repel each other when the current goes in opposite directions. | + | Based on the above calculations, the maximum magnetic force acting on each wire for a 4.5 A current is $2.03*10^-5$ N. Using the right-hand rule, or checking the signs of the calculated forces, you'll find that the wires attract each other when the current goes in the same direction, and the wires will repel each other when the current goes in opposite directions. |
