Two long, parallel wires, each having a mass per unit length of 25.0 g /m, are supported in a horizontal plane by strings l = 5.00 cm long. When both wires carry the same current I, the wires repel each other so that the angle ? between the supporting strings is 10.0 °. Find the magnitude of the current. (Your result must be in units of Amperes.  Include 1 digit after the decimal point and maximum of 4% of error is accepted in your answer.Take gravitational acceleration g = 9.81 m /s 2, vacuum permeability µ 0 = 4π x 10 -7 T /A 2 and π = 3.14.)

Magnetic Force

A magnetic force arises when a charged particle or a current-carrying conductor is placed in a magnetic field. It is created because of the movement of the charged particles.
