Part A: Two wires are running horizontially north and south.They are .1 meter apart and side by side. If they both carry 10amps of current in the same direction, what is the force betweenthem? Part B: If the current in one wire is 10 amps south andthe other wire is 10 amps north what is the force betweenthem? Part C: Suppose that rather than being side by side, the wireswere above and below one another. What would happen if the currentswere each 10 amps and in opposite directions? If the top wire had aweight of 1x10^-4 newtons/meter and the bottom wire was fixed couldthey force each other apart?

Explanation / Answer
forced between them F = i i ' / 2 r where = permeability of free space = 4 * 10 ^ -7H / m i = i '= 10 A r = 0.1m substitue values we get F = 2* 10 ^ -4 N
