First sprinkle iron filings on a glass plate well scattered. Now place a bar magnet under the surface of the glass plate and give light jerks continuously to the plate. Gradually the iron filings would be arranged in curved lines. More filings are found concentrated near by the poles. These curved strutures stand for the magnetic lines in the vicinity of the magnet. Actually magnetic lines of force are only imaginary lines.

Imaginary lines of force around a magnet?
Magnetic Field!
Where is the magnetic force the greatest on a magnet?
The magnetic force of a magnet is strongest at its poles. This is because the field lines of the magnetic field are most concentrated at the poles where they enter and leave the magnet. At the poles the magnetic field is strongest and the force is the greatest. The north pole is where the magnetic field lines enter the magnet. The south pole is where the magnetic field lines leave the magnet. The magnetic field lines are most concentrated at the poles. The magnetic force is greatest at the poles.
What is the area around a magnet that has the force of magnetism called?
The magnetic field surrounds the magnet. The lines of magnetic force repel each other, ultimately forming a sphere of decreasing strength.
What is the imaginary line that helps us visualise a electric or magnetic field called?
They are force field lines at right angles to each other as depicted in the related link.
What do the lines around a bar magnet?
magnetic lines of force
What are the lines of force around a magnet?
the imaginary lines around the magnet is a magnitic field and strong
What materials could you use to see the field lines around a magnet?
Magnetic powder, iron powder, etc.Iron Filings.
Are the lines that map out the magnetic field around a magnet?
no
What are lines called that map out the magnets field around the magnet?
They are called the magnetic field lines.
What are the lines called that the map out the magnetic field around a magnet?
They are called the magnetic field lines.
Imaginary lines of force around a magnet?
Magnetic Field!
What Is called when all of lines of force around a magnet?
The magnetic field.
Do field lines around a current wire look different from those around a bar magnet?
Yes. The field lines of a bar magnet emerge from one end, curve around, and stop at the other end. The field lines around a current-carrying wire are circles, with the wire passing through their centers.
Where are the Magnetic field lines closest together?
The field is strongest on the poles of the magnet (the ends of the magnet). More specifically, the 8 corners of the magnet are where the strongest magnetic field will occur. The weakest field occurs in the center of the magnet.
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.
Where is the field around a magnet is the strongest and where it is the weakest?
This shows the field lines around a disk magnet where the North pole is at the top. This shows the magnetic field strength around the disk magnet. Again, it is strongest in the corners, not in the center of the poles! The magnetic field is weakest in the middle of its poles!
Why are the poles the strongest part of a magnet?
Ever notice how a magnet works? Oh, sure, it picks up paper clips or tacks, but what are the paper clips or tacks doing? What they are doing is trying to get "into the magnetic field" of the magnet. The magnetic won't really pick them up very well along its side, will it? Nope. You see that now. But it picks stuff well on the ends. Here's the scoop. The magnet has magnetic lines of force running through it (inside it), and these lines of force emerge from one pole (or end), curve around the body of the magnet, and re-enter the magnet at the other pole (or end). The density of the magnetic field outside the magnet is greatest at the poles ('cause that's where the lines of force leave and return). The lines of force will always do this (leave a pole, go around, and go back in the other pole), but the lines of force pass through air around the magnet. They'd rather not do that if they have a choice. They'd rather pass through something that will "conduct" the magnetic lines of force. Like a paper clip. Or a tack. Or a lot of them. Iron filings will work, too. Any ferromagnetic material. Ferromagnetic materials that the magnet acts on will "get into the lines of force" if those materials (tacks, paper clips or whatever) can move. That's why you see the "arrangements" of materials that the magnet has picked up. That's why the materials hang around at the poles (the ends) of the magnet. They want to get into the magnetic flux lines, and want to get into as many as they can.
