Ive heard it said that electricity and megnetism are brought about by electromagnetic waves, but arent electric forces the cause of the other 2?
TheTankEngine said:the wave is caused by alternating motion of charged particles because light, or the electrostatic force, has a speed limit, right?
TheTankEngine said:i also don't get why an electromagnetic wave is considered electric and magnetic forces oscilating perpindicular to each other.
by the way, can you tell me where you learned and where i might learn online?
The source of electric forces is charged particles, such as electrons and protons. These particles exert forces on each other due to their electric charges.
Charged particles create electric forces through their electric fields. Electric fields are created by the presence of charged particles and can exert forces on other charged particles within their vicinity.
No, electric forces can be either attractive or repulsive depending on the charges of the particles involved. Like charges (positive-positive or negative-negative) repel each other, while opposite charges (positive-negative) attract each other.
No, non-charged objects do not experience electric forces as they do not have an electric charge. Only charged particles can experience and create electric forces.
As the distance between charged particles increases, the strength of the electric force between them decreases. This is known as the inverse-square law, which states that the force is inversely proportional to the square of the distance between the particles.
