What is the differences of electrostatic and electromagnetic force?

Answer 1

Electrostatic force is the force between static (not moving relative to each other) electric charges. Electromagnetic forces are any interactions due to photon exchange and INCLUDES electrostatic forces.

Coulomb's Law provides the electrostatic force between two objects.

#F=(q_1q_2)/(4piepsilon_0r^2)#

where #q_1# and #q_2# are the charges on the two objects, respectively, and #r# is the distance between them. This force can either be attractive or repulsive depending on whether the charges are opposite or same.

The forces that result from charges moving in close proximity to one another, creating magnetic fields and feeling the force of those charges, are collectively referred to as electromagnetic forces. These forces also include electrostatic forces.

Electrostatic force is the attraction or repulsion between electrically charged particles at rest, while electromagnetic force encompasses both electrostatic force and magnetic force, which is the attraction or repulsion between electrically charged particles in motion or between magnetic poles.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
