It's amazing to find some coating materials can have COF of static & Kinetic be equal. Like Teflon, if it's placed on two surfaces COF of S&K = 0.04

I agree. Friction = COF x Normal Force I assumed, by increasing N friction would not increase. But indeed it will, but maybe the limit is when the object breaks.

Ah, I remember in my Physics class that the COF stays constant no matter what, wasn't sure till now. Indeed, if the force of x increases the physical properties of that object could get damaged.

Two surfaces are placed. Surface block with the surface of the ground. The Coefficient of Friction (COF) is 0.1 between them. Friction is because of force acting downwards. The force is = x. By increase "x" to 100 times, will friction increase? I assume yes, but isn't there a limit?

We agreed that there are no magnetic force's acting when moving horizontally. Because the magnetic force act's only perpendicular to the surface. I noticed when moving a magnet over a ferromagnetic surface, only force resisting me is friction. But when I get to the edge,and the magnet is off-set I feel a strong magnetic force attracting the magnet back. There is indeed a weak lateral magnetic force, only at the edge. I'm wondering how could there be a magnetic force laterally and strong at the edge?

To note. There is a magnetic force being applied at the edge. A magnet is placed on the edge of a steel plate, notice there is a lateral force pulling the magnet closer inward. I assume the magnetic field is trying to expand more into the ferromagnetic material.

Thanks Studiot, I knew that. If this new technology is commercialized we can created two surfaces and coat this bad boy on them. And its pure carbon(or diamond), not a good conductor of heat or electricity.

I discovered a carbon coating material that will soon be commercialized. And the numbers are amazing! check this. This coating could make the COF = 0.001 - 0.006 Now that's almost frictionless! My goal is to reach such a number in our mechanics. And I think that will happen very soon!

Is it possible to drop the coefficient of friction from 0.1 to 0.01 or 0.001?

Okay, We got off wrong here. Let's go back, so the burning match is what kind of energy? And the internal energy is the fuel? The output would be = the match + internal energy of the fuel? Studiot your point was not very clear. Please clarify.

What I meant by input energy is the total amount of energy inputted to give out a certain output. The output Im referring to is the large explosion. I assume the internal energy is like a stored energy that is converted to give an output, in our case the internal energy we can categorize it as "input".

Well of course. Ein = Eout But the real world: Ein = Eout + losses

To what limit can I reach with the decrease of the Coefficient of Friction? Say we have a surface that is 0.1, is it possible to make it 0.01 or 0.001? I believe it might be probable. By perfectly(well, semi- perfectly) cutting the surface of the materials, and also adding ultra-lubricants to the mix to get such a result.

Say we have a burning match(Energy in the form of heat + light) and a barrel of Fuel. I threw that match into the barrel got a HUGE explosion out of it! The total inputted energy is the burning match + chemical potential energy in the fuel right? The output would be a larger explosion( that is more heat and light)? Im I getting this right?

Of course it has important uses. But I already know the potential uses of such a systems. However, never knew the methods to reduce the Eddy currents. They can cause a lot of heat, and unwanted resistance to the motion.
