Consider two small circular current loops. Suppose one loop is placed above the other (but not touching), with their areas oriented similarly. Do the loops repel, attract or have no effect when the currents are in the same direction? In the opposite direction?

    do the right hand rule: thumb in direction of current on each, fingers curl in direction of magnetic field. They attract in if current in same direction.
