If length of current carrying conductor increases, what is the effect

1.	If length of current carrying conductor increases, what is the effect on the force?(a) increases(b) decreases(c) remain same(d) become zeroI had been asked this question during an interview.My query is from Magnetic Field Due to an Electric Current topic in chapter Electromagnetism of Basic Electrical Engineering
Answer» RIGHT choice is (a) increases The best I can EXPLAIN: Force of infinite conductor is given by Bil if B, i, l are mutually perpendicular F/l = Bi = µ0i1i2/2πd if d is a SEPARATION of two infinite parallel conductors. So, as LENGTH of conductor increases force increases.
