WebFormation of electromagnetic waves. When an electric charge oscillates, it gives rise to another oscillating magnetic field. This is because a moving charge is known to produce a magnetic field and vice versa. Therefore, the oscillating magnetic field will also generate more electric fields. As this repeated generation of electric and magnetic ... Web13 de fev. de 2024 · X-rays can be produced naturally or by machines using electricity.
