2. The electromagnet below has a current of 2.5 A and 500 turns and a length of 15 cm. (The picture shows the correct direction of current, but does not represent the number of turns.) It has an iron core, that we need to find and use the permeability of iron and not μo in any equations. The wire next to it carries a current of 7.5 A and is 5.75 cm away. The wire is centered on the face of the electromagnet. Find the force per unit length of the magnet on the wire.
