Field from Two Wires

Two infinitely long straight wires each carry $100$ units of electric current. Wire $1$ passes through point $(1,0,1)$ and is oriented in the direction of vector $(1,2,4)$ . Wire $2$ passes through point $(-3,1,2)$ and is oriented in the direction of vector $(-2,5,3)$ . There is a test point at position $(2,-3,5)$ .

What is the magnitude of the net magnetic flux density $(B)$ at the test point?

Details and Assumptions:
1) Magnetic permeability $\mu_0 = 1$
2) The electric currents flow in the directions of the given vectors
