Relative

I can make one of those thanks I understand what is happening from the youtube video, but see something else is happening. But will keep quiet. Sorry I have got to ask and it is on topic, we are talking electricity, ok , we add electrons to mass, to make the strips repel, I thought all mass already contained electrons because it was atoms,? So why does mass not repel mass if there is electrons in mass? In a lifter, an electrical field is generated, electrons, so what electrons does the lifter repel to lift? Does the lifter repel the electrons of the earth?

Thank you for the link, I had better not tell you what I thought and stick to topic. Ok , I have got to ask, I am in agreement with most of what you said about the link, however one point I have to mention, you say the heat of the green house gases returns some back to the earth, I have got to ask this, If heat rises, how can it return to the earth?

Yes i think i am misunderstanding torque, and I have used a torque wrench at that,

Probably my definition of fn , but still on subject, what I was trying to say is that the N is attracted to its S in a singular ,a few posts up, the force in the center of the magnet is equal to zero like the fn you use on the ground, north polarity equal to the south polarity with inwards force in itself?

Pfff, i so want to go off on a rant about this. The electrons are attracted to the metal strips? The metal strips contain no electrons to start of with?

Thank you , and yes arguably about direction, so if i changed the bar that holds the rectangle to an elastic band, what torque if any is inwards?

''OK. "Are the north pole and south pole of a single magnet attracted to each other?" I suppose they are. I have never thought about that before.'' I put fn at zero on my diagram, so would the force of a single magnet by its own action of forces have a central point that the force was Fn=0?

I know lol, but much easier to consider big than small when considering what questions to ask. I suppose I am just confirming what I have learnt, and been correct in my understandings. I am avoiding speculations, and just refreshing on the knowledge. Magnets have a magnetic flow that always follows north and south of the earth in magnetic terms? Magnets allow the Earths magnetic energy to be harnessed through them and amplified?

Sorry I thought a magnet had a + and - polarity What I was asking is when a magnet is whole, A north polarity is attracted to a south polarity of another magnet , so a magnet as a singular, on itself , still has a North and South Polarity,so throughout the magnet is the north still attracted to the south, and the force direction inwards centripetal has in my diagram above? Also If we had a 10m magnet and stood it vertical south polarity on the ground, north in the air, would the north magnetic field push the magnet over towards the south magnetic pole of the planet?

I said this in another thread, but did not not word it that good- Currently it is absorbing slightly more energy than it loses. Hence: global warming. ''It is slightly more complicated than "can hold more". It is to do with how transparent the atmosphere is to infra red.'' What do you mean by this?, please explain the part in bold,

''Ditto. What do you mean by "how much"?'' The Earth emits energy? The Earth also absorbs energy from the sun? What amount of energy is released, compared to the energy gained? If the energy was not released, what quantity of energy could the Earth hold before there was any significant effects? By greater carbon in the atmosphere the atmosphere can hold more heat also by Thermodynamics? In thermodynamics if we had two house bricks that were heated to their maximum state, loss would be equal to input?

My apologies , the pivot point is motorized if that helps. So what direction is the torque centrifugal?

approximately zero. well yes. and isnt a magnet also a force equal to zero, you answered yes that the opposites attract in magnetism, so a minus and plus standard magnet the polarities are attracted to each other to the central point? ''You mean the bit in the middle of the magnet? I'm not sure how to answer that as it is the magnetic field outside the magnet that interacts. This is due to the whole magnet but is strongest at the ends.'' Yes in the middle of a magnet

Thank you for the answers, and thank you for showing me the electroscope device. How does that work? is it the atmosphere you charge or is it the needle you charge?

OK so your answers I have put into diagram form. Is this a correct diagram of magnet interaction? and what is the effect of the main body in this diagram,attract or repel? would the magnet be 50% positive polarity and 50 % negative polarity, where there is a central point of the the two meeting? ? The earth and the suns magnetic poles are this way around? Earth been the smaller circle

I am sorry I do not understand what you have put, Is torque not in the direction of this diagram in this process? If not , could you possibly edit my diagram and put in the torque tag?

Increases volume, you mean it expands becoming less dense but keeps its mass conserved at all times?

Lightning contains electrical energy? Lightning is attracted to a negative? The ground emits a negative when Lightning is involved? Kinetic energy contains/makes, electricity? I will re phrase the earth question emitting, the Earth produces Electrical energy? The Sun produces electrical energy?

Heat capacity sorry.

How much energy can be absorbed by Helium compared to air?

In a reference frame of an object been rotated from a central point on a bar in a circular motion, is the torque directed along the bar centrifugally with no centripetal force acting on the bar?

Does an equal polarity of the same magnetic force, in magnetism, repel and not attract?

In electricity, I often see + symbols and - symbols, positive and negative, I often have touched two positives together on a low voltage system, meaning a battery, to see sparks! Is it a correct assumption that two equal polarities can not touch and force each other apart? Does the Sun emit electrical energy? Does the Earth emit electrical energy? Does a positive attract a negative when talking about electrical energy?

How much energy can a house brick absorb? How much energy can the Earth absorb? If by thermodynamics a magnet starts to reach its curie point and loses its magnetism force, what effect is the thermodynamics having on the molecules in the magnet? Hot metal expands, and increases mass by adding energy/heat, what on a molecular level is happening?

For example how much energy can a house brick absorb?
