Why is the following situation impossible?

[physics=world]

1. Why is the following situation impossible? Two parallel copper
conductors each have length , L = 0.500 m and radius
r = 250 mm. They carry currents I = 10.0 A in opposite
directions and repel each other with a magnetic force FB =
1.00 N.

3. I am thinking that it would be impossible since the magnetic field would cancel. is this right?

 

[altamashghazi]

no they would not cancel

I think i need help understanding if this is two long parallel conductors or is it a circle?

 

[altamashghazi]

opposite current carrying rods repel each other
