Could someone help me with this problem? I don't really know how to do it..

What is the magnitude and direction of force acting on wire 1 due to the magnetic field produced by wire 2?

This type of problem is a huge deal, you should attempt to master it. It uses the Lorentz Force.

On that site too, here it has specifically the paraelle wires.

And since the currents are opposite, should repel from eachother. Oh yeah, was there a length of one of the wires given too? I'll have to dig out my book, think it derived 2 infinite wires, I'll get back to you on that.

Unless the length of the wire is known, you'll have to specify the force per unit length.

Often, in problems like this, "force" is loosely asked for when really it should be "force per unit length". So, make sure you give the answer in the correct units.
