1. A long, straight wire is carrying a current of 5.0 A in the direction shown in the
figure. The point P is 0.040 m from the wire.
What is the direction of the magnetic field at point P due to the current in the wire?
Answer: out of the plane of the page
I can only see that the current is to the left. I don't understand how to figure out the direction of the magnetic force. :(
