Mutual action of force of two coils with the flow

icon

According to Ampere's rule right-hand rule for coils to induce poles with the same orientation. Since opposite poles of the magnets (and therefore the coils) attract, draw the coils together. If you mount the coils on the contrary, induce the same poles of the coils, so the coils will repel.
