What m is a force that attracts iron?
Gravity is a force that attracts all matter.Magnetism attracts only a few elements.
How does moving magnet generate electricity?
magnet moves cause all magnets have an electric field around it]
How does a noncontact force create a force against an object?
It is helpful to consider that some forces express themselves in what is called a field, and this field "surrounds" the object that has that force associated with it. We're familiar with a couple of the basic forces that do this, and gravity is one such force, while electromagnetic force is another. Let's look at them. If we consider gravity, it is reaching from the sun to all the planets (and other things in solar orbit) and is holding onto them. Earth is some 93 million miles from the sun, but the sun has held it in orbit for billions of years. Gravity can reach through the vacuum of space and grab a hold of things. It does, and we're glad for its effects. In electromagnetics, we see that the magnetic force reaching its invisible field lines out around the source to interact with ferromagnetic materials around it. If we have a sheet of glass, iron filings and a magnet, we can set up a demonstration. We can put the magnet below the sheet of glass to move the iron filings on the glass. The magnetic field (the field lines) will "reach through" the glass to interact with the iron filings, and we see the effects when we move the magnet. The forces are expressed in the field that is the "force carrier" of the "thing" that has the force associated with it. If we think of the "force field" around the object that has the force associated with it, then it is easier to see that the field can interact with other objects or materials. And it can do so without the object with which the force is associated having to be in contact with other objects on which the force is acting.
What is a definition of magnetic field lines?
The magnetic lines of force are not real, they are imaginary lines of force which we draw using a north pole. We can draw as many as we desire using a different starting point for our drawing of lines of force. (Of course, we say that we say that when the strength is more we draw the lines closer and when it is less, we draw them sparse, but it is still subjective, one can start at a different point and draw as many lines .how can we depend on the number of lines for the definition of flux? Is there no better definition? We can straight forward define it as perhaps which is less ambiguous.
Does a magnets pull force match its push force?
Yes. I used a wheel and placed magnets all around it, then I spun the wheel and placed another magnet in front of the wheel and thought that the wheel would keep spinning due to the magnets repelling each other but it didn't work.
What Is called when all of lines of force around a magnet?
The magnetic field.
What is electromagnetic flux?
The electromagnetic force is a force that is expressed as (or that "shows up as") a "field" or a "group of lines of force" around the source. Electromagnetic flux is a direct reference to those magnetic lines of force. Electromagnetic flux is the electromagnetic field or the group of electromagnetic lines of force around the source. All the following sentences say the same thing: The electromagnetic flux around the magnet was very high. The magnetic flux around the magnet was very high. The magnetic field around the magnet was very large. The flux around the magnet was very high. The field around the magnet was very large. There were a large number of magnetic lines of force around the magnet making the field strength very high.
Can magnetic lines of force travel through vacuum?
There ARE no magnetic lines of force. The magnet and iron filings demonstration causes the illusion of lines, but if you take a picture of the "lines" and replace the paper and iron filings, the "lines" will appear in a different place. But if there WERE lines of force they probably could exist in vacuum.
what point on a magnet will the magnetic force be strongest?
The highest concentration of magnetic lines of force is at the poles of the magnet. It's that simple. Here's why. The lines of force are all "bundled together" inside the magnet, and run its length to emerge at one pole. Then the lines of force spread out to "go around" or "surround" the magnet to reach "around" to go back to the other pole. Then they concentrate at that other pole to return to the inside of the body of the magnet. Use the link to get more information and see a diagram.On the Sun, the magnetic fields that create the prominences may be the strongest magnetic fields. On Earth, I'd guess that those used in MRI machines would be right up there, but the fields used to steer particles in the hadron collider may be worth a check as well. I have no numbers readily available for you.

Electric lines of force never cress Why?
I think you mean "cross". And furthermore I think you mean the old iron filings around a bar magnet demonstration showing "magnetic lines of force". With all this guessing I propose an answer that your teacher won't like either: They don't cross because they don't exist. To prove this-- Sprinkle the iron filings on paper with a magnet beolw the sheet. Notice that they don't move. Photograph it. Do the experiment again. Photgraph this too and compare the two photos. They will be quite different showing that the "lines of force" are only an artifact of iron filings being sprinkled onto the paper.
Do the magnetic lines of force actually exist explain?
Yep they are called lines of flux, I believe. While invisible to the naked eye, like wind, we can see their effects. If you have iron shavings and a bar magnet, place the bar magnet on a piece of paper, then sprinkle the iron shavings all over the paper. The vast majority of them should line up along the lines of flux between the north and south pole of the magnet.
What is a force that wraps around a magnet?
magnetic pull
Is it copper or what magnetic force around a magnet?
The magnetic force around a magnet can be a lot of things. Just some things are stronger and some are less strong. Copper is absolutely not magnetic at all, you can experiment that by trying to pick up a penny with a magnet. I am not sure what is the magnetic part of a magnet, but I think it might be close to iron. Something like that. I do know though what is attracted to magnets. Iron, bolt, paper clips, and the metal part on scissors.
If you draw the lines of action of all the force on the board and extend the lines what will you get?
You will get a meaningless jumble of lines.
What happens to the magnetic field of a wire when you change the direction of the current of the wire?
If iron piece is place in its field, the direction of the magnetic lines of force change towards North and South as in the case of a magnet. North represents North Pole and South for South Pole.
What is the space around a magnet where the forces of the magnet act?
The space around a magnet where the force of the magnet can act is the space occupied by the magnetic field. Alternatively we say that the magnetic field acts in the space around a magnet. That is a very qualitative statement with little predictive value. More predictive value is contained in a statement that the strength of the magnetic field at any position in the vicinity of a magnet is measured by the torque which is exerted on a small magnet moment (compass) place in the vicinity of a magnet. This, recorded with the direction the test compass points is actually a mapping of the magnetic field of a magnet. As a side note, if carefully measured one discovers that strength of the field around a magnet decreases as the inverse cube of the distance when far from the magnet. The field is mostly in the volume near the magnet but the weakening field continues to exist at all distances from the magnet.
