Description
In this article, it's showed an experiment about the influence of the magnetic field produced around an electrically charged conductive wire with direct current on magnetically susceptible objects. There were used three compasses previously inspected to verify the alteration of their orientations, favorable to the magnetic field generated around the conductive wire, which passes over the compasses, and connected to a resistor, such as the experiment performed by Oersted in 1820, which proved that a direct current directed electric field generates a magnetic field, where until then, electricity was dissociated from electromagnetism; thus found that a conducting wire is capable of changing the direction of a needle previously positioned to true north.
