Can an electromagnetic wave be deflected by electric or magnetic field.
Welcome to the PF.
What is the context of your question? Have you seen something in a science book or journal that suggests that this can happen? Under what conditions?
Interaction between two independent waves can only occur if the common environment they are propagating through is non-linear. Non-linearity means that the characteristics of the material are modified by the presence of other waves. Non-linearity is common in crystals, but free space is linear.
