An example of electromagnetic force is when your hair stands up because of a balloon. This is because two objects are electrically charged and are either attracted to each other or push each other away. If two objects have the SAME charge, what happens? If two objects have OPPOSITE charge, what happens?
Same charge repulse or push away from each other
