Answer:
Light is an electromagnetic wave. What that means is that it is an oscillating electric and magnetic field. An electric field, is what causes the attraction between a positive and a negative charge. A magnetic field cause the attraction between the North and South poles of a magnet. In light, the strength of these fields changes with time and place.
