Electric and magnetic fields in electromagnetic radiation form a transverse wave: they are oriented at right angles to each other and to the direction the wave travels. As the wave propagates, the electric and magnetic fields oscillate in sync, reaching their peaks together. This perpendicular arrangement captures the essential spatial relationship between the fields, which is why describing them as oscillating fields positioned at right angles to one another is the best description.
