A long straight conductor carries a constant DC current in a uniform magnetic field of 30uT north. Calculate the magnitude and direction of the DC current if at a point 5.0cm above the conductor the net magnetic field is zero.
So I calculated that the current is 7.5A, but I don't know which right hand rule to use to figure out the direction.
Please help, thankyou!
