'pull' & 'push'- electromagnetic force?

AI Thread Summary
The discussion explores the connection between push and pull forces and electromagnetic interactions. When pushing an object, the repulsion between the outer-shell electrons of the contacting atoms prevents physical contact, illustrating the strength of electromagnetic forces. The concept of pulling is clarified as effectively a form of pushing, as it involves wrapping around the object being moved. Additionally, it's emphasized that electrons do not physically touch but instead interact through their electric fields. This highlights the fundamental role of electromagnetic forces in everyday interactions.

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?
 
Physics news on Phys.org
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.
 
Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'
So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
