Defennder said:You need to be careful as to how you use the terms here. The electromagnetic force is comprised of both the electrostatic force and the magnetic force. If the 2 charges are stationary then only the electrostatic force is present. If one is moving you have to take into account the induced magnetic field.
The force between the nucleus and the electron is electrostatic, since the nucleus comprises of protons and neutrons which attract the electrons.
Electric force is a fundamental force in nature that is responsible for the interactions between electrically charged particles. It is a force that can attract or repel charged particles, and it is responsible for many everyday phenomena, such as static electricity and the flow of current in wires.
Electromagnetic force is a combination of electric and magnetic forces. While electric force is responsible for the interactions between charged particles, electromagnetic force also includes the interactions between moving charged particles and magnetic fields. It is a stronger force than electric force and is responsible for many phenomena, such as light and radio waves.
In atoms, the positively charged protons in the nucleus are held together by the strong nuclear force. However, the negatively charged electrons are held in orbit around the nucleus by the electric force. This force keeps the atom stable and determines the properties of different elements based on the number and arrangement of electrons.
The strength of electric force follows an inverse-square law, meaning that it decreases as the distance between charged particles increases. Specifically, the force is proportional to the product of the charges and inversely proportional to the square of the distance between them. This means that the force becomes weaker as the distance between charged particles increases.
Electric and electromagnetic force have numerous applications in our everyday lives. Some examples include the generation and transmission of electricity, the functioning of electronic devices such as computers and phones, and the use of electromagnets in motors and generators. These forces also play a crucial role in medical imaging technologies such as MRI machines and in communication technologies like wireless internet and cell phones.
