2. Two long current-carrying wires run parallel to each other and are separated by a distance of 4.00cm. If the current in one wire is 1.25 A and the current in the other wire is 3.00 A running in the opposite direction, determine the magnitude and direction of the force per unit length the wires exert on each other.3. a lab experiment, two long parallel wires are separated by a distance of 2.75 cm. One wire carries a current of 1.55 A while the other Carrie's a current of 3.45 A. The currents are the same direction. ) What is the magnitude of the force per unit length m) that one wire exerts on the other

Use the worked example above to help you solve this problem. A wire carries a current of 21,7 A from west to east. Assume that at this location the magnetic field of Earth is horizontal and directed from south to north and that it has a magnitude of 5.00 x 10- T. (a) Find the magnitude and direction of the magnetic force on a 33.3 m length of wire. N upward (b) Calculate the gravitational force on the same length of wire if it's made of copper and has a cross-sectional area of 2.53 x 10-6 m2. N EXERCISE HINTS: GETTING STARTED | I'M STUCK! What current would make the magnetic force in the example equal in magnitude to the gravitational force? I = A A large current would very rapidly melt the wire. Need Help? Read It
