Electromagnetic Repulsion

[Shriraksha]

Main Question or Discussion Point

Can EM radiations produce repulsive effect on on non magnetic objects? If yes how can such fields be produced?

 

[mfb]

Anything which can absorb, deflect or change the direction of electromagnetic waves (basically everything with electric charges) will feel a force from them - and at least some part of the force has to be in the direction of the incoming radiation.
