    Default Are opposite forces the same?

    What is the difference between opposite forces and the same force in opposite directions facing each other?

    If a positive and negative attract each other and keep each other in balance, what stops them from hitting or touching each other?

    When I consider magnetism, opposite forces are in the same direction.

    Is there negative force? A simple switch of relativity can change a negative force to positive, at least everything that I can think of, which is not much, unless it punches me in the face.

    Is there any examples or experiments that prove negative force, without relative?

    What?? Explain, please.

    When I see a picture of one type of magnetism, the type that has one side pulling while the other side is pushing, the arrows flow in many directions. But right down the middle, the arrows show pulling and pushing in the same direction, not opposite, they appear to be the same force, forcing in the same direction.

    What little I know about math, I know less about magnetism.

    Thanks for reading and responding. Hopefully that explains what I am trying to understand better.

    Which diagrams? Not sure of what you're talking about.

    No problem

    I went to Wikipedia and looked up magnetism, I know is not a great source, but I'm guessing the diagrams are accurate. They show many types of magnetism, some way to complicated for me. I try to stick with the simplest. It is my only chance to understand anything.

    Thanks again.

    Link to one that shows "right down the middle, the arrows show pulling and pushing in the same direction, not opposite, they appear to be the same force, forcing in the same direction."

    There are certain misconceptions about magnetism fostered by conventions in illustrating magnets. For instance sometimes you see poles North N as + and South S as -. This incorrectly implies that, like electricity, North has positive charge and South negative. The polarity has nothing to do with electric charge.

    When opposite poles point toward each other the effect of the force of magnetism attracts. When they are the same pole the effect repels. The force is magnetism. You're asking about the effect of the force not the force itself.

    I hope this makes sense based on what you wrote. I don’t know much about electricity either, unless I can attach it or plug it in. You would be right to ask me what I am doing here.

    I tried to imagine if I could go thru magnetism, that is probably what started my confusion. Can you tell me more about the point where it originates? Is it a single point or two? I’m trying to think if it is the same force or if it is two different forces and if there is a wall or border that would prevent something from going thru the side of pulling to the side of pushing, if that is possible at all. If enough force was applied, could it be possible? (Assuming the magnet doesn’t break)

    If two magnets were taken far into space, does magnetism work the same?

    How does a compass work in space, if at all?

    As the force travels outward, based on the arrows, what is forcing them to turn back on itself and not continue straight outward? Spinning. The spinning of the two points in time. My best guess. I tried to think of magnetism as a wave, I can’t make sense of that at the point magnetism hits space.

    I hope that is not too many questions.

    Thanks astrotech.

    Those lines you see in the diagram are just illustrations of the field strength and orientation of the polarity of the magnetic field in the space around the magnet. (So that answers the question about workning in space. Yes they do the same thing in space.)

    Think of all the lines made of little compases. The needles of the compases over the middle of the magnet point north south horizontal to the surface of the magnet. The needles over the poles point at the pole vertical to the surface.

    Really in physics we play with stuff like magnets and describe the effect we see and theorize about why they do it. You should get some magnets and play with them. Describe the effect you see. You are writing about magnets as you read about them but never played with them.

    To play with magnets you should look up things other people do with them. For instance play with two of them. Play with one with iron fillings, with compases, with a sewing needle on a thread, with a magnetized sewing needle on a thread.

    I have played with them, tried to imagine how they work, not being a scientist, I don’t get very far. I will try again.

    You have explained well enough even for me to understand better. That force and magnetism still blows my mind. Where does it come from, when I have seen images of it at the sun, it changes, comes and goes, at least at the same point.

    I have much to read and learn if I want to understand it better.

    Thank you much for giving your time.
