Field (pheesics)

A field is a pheesical quantity that haes a value for ilka pynt in space an time. For example, in a wather forecast, the wind velocity is describit bi assignin a vector tae ilka pynt in space. Ilka vector represents the speed an direction o the movement o air at that pynt.

The magnitude an direction o a twa-dimensional electric field surroondin twa equally charged (repellin) pairticles. Brichtness represents magnitude an hue represents direction.
