Three long, parallel conductors each carry a current of

I = 1.80 A. The figure below is an end view of the conductors, with each current coming out of the page. Taking a = 0.60 cm, determine the magnitude and direction of the magnetic field at the following points.

Is b= (uI)/(2pir) the correct formula to use here? and could you please explain the process as how to solve for the points

Use the right hand rule we talked today in class, the B-field's directions can be found. The magnitude can be found with the Ampere's Law result for the infinite straight wire: $B=\mu_0I/2\pi r$.
