'pull' & 'push'- electromagnetic force?

In summary, the origin of push and pull can be traced back to electromagnetic forces. When we push an object, the electrons in the outer shells of the atoms making up the materials will repel each other due to the force between like charges. This explains why we can't walk through walls. Pulling an object is actually a form of pushing, as the hand, rope, or chain is wrapped around the object. It is important to note that electrons do not physically come into contact with each other, rather their electric fields repel each other.

how can wec trace the origin of push and pull to electromagnetic forces? I mean when we push a thing what actually are we doing? What are the atoms at the contact surface actually doing?

The electrons in the outer shells of the atoms making up the materials coming into contact will repel each other with the (very strong) force between like charges. That's why you can't walk through walls, even though you and the walls are mainly empty space.

Note that when you "pull" an object, whether with you hand, a rope, chain, etc., you are wrapping your hand, rope, etc. around some part of the object so it really is a "push". Oh- and electrons don't actually "come into contact". Mentz114 meant that their electric fields repel one another.
 

What is the difference between 'pull' and 'push' electromagnetic force?

'Pull' and 'push' electromagnetic forces are two different types of interactions between charged particles. 'Pull' force, also known as the attractive force, is when two opposite charges are attracted to each other. On the other hand, 'push' force, also known as the repulsive force, is when two like charges repel each other.

How are 'pull' and 'push' electromagnetic forces related to the electromagnetic spectrum?

'Pull' and 'push' electromagnetic forces are both part of the electromagnetic spectrum. The electromagnetic spectrum is a range of all types of electromagnetic radiation, including visible light, radio waves, microwaves, infrared radiation, ultraviolet radiation, x-rays, and gamma rays. 'Pull' and 'push' forces are responsible for the interactions between charged particles that produce these types of radiation.

What are examples of everyday applications of 'pull' and 'push' electromagnetic force?

'Pull' and 'push' electromagnetic forces have many practical applications in our daily lives. Some examples include the functioning of electric motors, generators, and speakers. These forces are also used in electronic devices such as cell phones, computers, and televisions. In addition, 'pull' and 'push' forces are responsible for the attraction and repulsion between magnets.

How is the strength of 'pull' and 'push' electromagnetic force determined?

The strength of 'pull' and 'push' electromagnetic forces is determined by the magnitude of the charges and the distance between them. The greater the charge of the particles and the closer they are to each other, the stronger the force. This is described by Coulomb's Law, which states that the force between two charged particles is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.

Can 'pull' and 'push' electromagnetic forces be shielded or canceled?

Yes, 'pull' and 'push' electromagnetic forces can be shielded or canceled by using conductive materials. Conductive materials, such as metals, can block or absorb electromagnetic radiation, preventing it from reaching the charged particles and reducing the force between them. Similarly, opposite charges can cancel each other out, resulting in a net force of zero.
