Final answer:
An electric current always produces a magnetic field that is perpendicular to the field.
Step-by-step explanation:
The correct relationship between electric current and the resulting magnetic field is described by the right-hand rule. According to this rule, when your right thumb points in the direction of the electric current, the curled fingers indicate the orientation of the magnetic field. It's essential to note that the magnetic field generated by an electric current is always perpendicular to the direction of the current and parallel to the electric field. This principle, widely applied in electromagnetism, underscores the intricate connection between electric currents and the associated magnetic phenomena, offering valuable insights into the behavior of charged particles in various contexts.
