1. A straight conducting wire carries a 8.0A current in the +y -direction.
Part A. Find the magnitude of the magnetic field that results in a force per unit length on the wire of 0.12N/m in the -z -direction.
Express your answer to two significant figures and include the appropriate units.
Part B. Find the direction of the magnetic field that results in a force per unit length on the wire of 0.12N/m in the -z -direction.
