As the magnetic fields of the magnet and current in a circular wire are the same Ampere assumes that the molecules of substances have circular currents - currents elementary equivalent of small magnets . In non-magnetic content state of substances these currents are disorderly , their magnetic fields have all sorts of directions and cancel each other out
