Two parallel currents

1. The problem statement, all variables and given/known data

Two current carrying wires run parallel. The bottom wire creates a magnetic field at a point on the top wire. What direction is the force on the left wire?

2. Relevant equations

I’m assuming there’s no equation, just the right hand rule..?

3. The attempt at a solution

I think this problem asks for the right hand rule, but I’m not sure. I don’t have a very good grasp of the right hand rule… I’m assuming it is dependent on the direction of the magnetic field and something else.

Please help!
