A 0.2 kg conductor of length 0.8 m carries 2 ampere current to the right in a magnetic field. What is the magnitude and the direction of the magnetic field acting on the conductor if the net force on the rod is zero? (Assume that the rod is hung by two insulating supports.)

I'm not sure if the question is wrriten well enough
But basiclly if there is no force on the rod, then B=0
or it is parralel to the current
