Question
Two wires,1.11cm apart are parallel to each other and of a length, L, carry current. Wire #1 has a current 1.23 A, while Wire #2 has a current of 2.79 A. If L = 27.6 cm, determine the magnetic force on Wire #2 because of Wire #1 if the currents are in the same direction. Determine the magnetic force on Wire #2 because of Wire #1 if the currents are in opposite directions.

Here ,
as the magnitude of magnetic force will be same if currents are in same or oposite direction
NOw, when the current is in the same direction
magnetic force on wire 2 = u0 * I1 * I2 * L/(2pI * d)
magnetic force on wire 2 = 4pi *10^-7 * 1.23 * 2.79 * 0.276/(2pi * 0.0111)
magnetic force on wire 2 = 1.71 *10^-5 N
the magnetic force on wire 2 is 1.71 *10^-5 N
the direction of force is towrads the wire 1
when the current is in oposite direction
magnetic force on wire 2 is 1.71 *10^-5 N
direction of force is away from wire 1
