Friction doesn't apply to a particle.
But in general, yes, frictional forces ariss from electromagnetic interactions between the atoms at the surface of the two objects.

It really depends upon which "level" you are looking at. From the "macro" level, friction is small projections in the surface hitting and perhaps breaking off against small projections in the object. From the "micro" level, it is the electric fields of the protons and neutrons pressing against one another.

Friction can be quite interesting. The Wikipedia article mentions situations when you can have friction even with zero or negative normal force. It gives adhesive tape as an example. Sometimes adding water (normally considered a lubricant) can also increase friction. For example many people lick their fingers when trying to turn the pages of a newspaper.

Friction is a force that resists the motion of an object when it comes into contact with another object. It is caused by the interaction between the surfaces of the two objects and is a result of the electromagnetic nature of matter.

Friction is not a single type of force, but rather a combination of different forces such as electrostatic forces, van der Waals forces, and surface roughness forces. These forces act on the particles at the point of contact between the two surfaces, causing them to resist each other's motion.

Therefore, it can be said that friction is a result of the electromagnetic forces between particles. This is because all matter is made up of atoms, which are composed of positively charged protons, negatively charged electrons, and neutral neutrons. When two surfaces come into contact, the atoms on their surfaces interact with each other through electrostatic forces.

In addition, friction can also be affected by the presence of magnetic fields. For example, in the case of a magnet sliding on a metal surface, the magnetic forces between the two objects can increase or decrease the amount of friction between them.

In conclusion, friction is a force that is applied on a particle and is a result of the electromagnetic nature of matter. It is a complex phenomenon that involves various forces and can be influenced by factors such as surface roughness and magnetic fields. As scientists, it is important to understand the electromagnetic nature of friction in order to better understand and manipulate this force in various applications.
