Which statement accurately describes the relationship between current and magnetic fields?

The statement that accurately describes the relationship between current and magnetic fields is that a current creates a magnetic field. This principle is rooted in electromagnetism, which states that when an electric current flows through a conductor, such as a wire, it generates a magnetic field around it. This effect is commonly illustrated through the right-hand rule: if you point your thumb in the direction of the current flow, your curled fingers will show the direction of the magnetic field lines that encircle the conductor.

The creation of a magnetic field by a current is fundamental to many applications, such as electromagnets, transformers, and electric motors. By understanding this relationship, students can grasp how electricity and magnetism are interconnected, which is essential in various scientific and technological contexts.
