1. The problem statement, all variables and given/known data This is not a homework Problem.Just a doubt. The cross represents current-IN. 1-Magnetic field lines are produced in clockwise direction when current is going IN. 2-When wires carry currents IN,they form clockwise magnetic fields.So the magnetic fields of two wires join,forming a loop which attracts them(This is what my teacher said) 3-What happens in the case of a magnet?It won't form a "loop" because the field direction of the outer magnetic field of the magnet is opposite to that of the wire(A).But the inner field is in the same direction.
