SUMMARY
When direct current (DC) flows through a wire, it generates a magnetic field around the conductor. The interaction between this magnetic field and external magnets is significant and depends on the wire's properties and the magnitude of the current. The strength of the magnetic field produced is directly proportional to the current flowing through the wire, influencing how external magnets will react in proximity to the wire.
