What causes Electromagnetic Force?
|
-
|
|
Three principles of Electromagnetic force:
|
1) All electrical changes attract or repel one another: like charges repel while opposite charges attract.
2) The force between charged objects is directly proportional to the amount of the electrical charge on each object. 3) The force between charged objects is inversely proportional to the square of the distance between the two objects |
