How are the directions of the electric and magnetic fields of an em wave related to each other and to the direction in which the wave is moving? Group of answer choices The electric field, the magnetic field, and the direction of the motion are mutually perpendicular. The electric field and the magnetic field are mutually perpendicular, but each runs parallel to the direction of the motion. The electric field and the direction of the motion are mutually perpendicular, but each runs parallel to the magnetic field. The electric field and the magnetic field are parallel to one another, but perpendicular to the direction of the motion
