The magnetic lines of force are invisible, you can not see them; but you can do the following experiment that will show you the effect that the magnetic lines of force have on iron filings.
Here is a simple experiment to observe magnetic lines of force from a magnet.
- Take a piece of cardboard and tape a bar magnet on one side.
- Now flip over the board and keep it horizontal such that the magnet is on the lower side.
- Place some white paper on top of the board and use clips, staples, tape or glue to keep it in place.
- Now lightly sprinkle some iron filings on the paper. They would arrange themselves randomly at first.
- Now, keep tapping the edge of the board very lightly, just enough to make the iron filings move a little.
- After a while, you will see the iron filings arrange themselves in a pattern. The pattern will be made up of somewhat elliptical (or circular) lines from one pole of the magnet to the other.
These lines are where the invisible magnetic lines of force are located.
They never intersect each other because the magnetic field of the magnet acts to repel each other.

∙ 6y agoAs magma rises as lava and cools to form rocks, any magnetic minerals in the rock (eg magnetite and haematite) align themselves with the earth's magnetic field. When the rock is solidified this magnetism is 'frozen' in the rock to form a weak, permenant magnet.
The direction in which they point can be measured by a cryogenic magnetometer.
This magnetic orientation can then be used to find where, in relation to the rock, magnetic north was. This leads to different rocks in continets showing different magnetic norths. As there is only one the continent itself has moved. Different samples will be taken from throughout the continent and the magnetic orientation is tested to find where magnetic north was. The position of magnetic north is plotted on a map to show apparent polar wander.

How can you see the invisible magnetic field?
You can make magnetic field lines with a magnet. You an use a permanent magnet, or an electromagnet.
Magnetic field lines curve out from one pole and return to the same pole?
No. Magnetic lines curve out from one pole and end up at the opposite pole. Please see the related links for illustrations.
Are the magnetic lines force of a bar magnets strongest at the end of the magnet or in the middle?
That is where the field lines originate and therefore where they are thickest. The thicker the field lines, the stronger the field. To see the magnetic field lines, cover your magnet with a piece of paper and spread metal fillings over it.
How could straight copper wire produce magnetic field lines?
The copper by itself will do nothing of the sort. It will be surrounded by magnetic field lines if a current flows through it. It is the current that produces the magnetic field lines.
Is magnetic field lines continuous?
Magnetic field lines are continuous. The lines outside the magnet go from north to south, while inside goes from south to north creating a closed loop. This is because there are no magnetic monopoles.
A magnetic field is described by magnetic lines of?
Lines of Force
What are the lines called that map out the magnetic field around magnetic?
They are called the magnetic field lines.
How can you see the invisible magnetic field?
You can make magnetic field lines with a magnet. You an use a permanent magnet, or an electromagnet.
What is the invisible force around a magnet called?
Have you ever seen a magnet? Did you see the field? There you go. While you can't see the field itself directly, you can see the effects of the field if you use iron filings or something like that; they'll line up with the magnetic field lines
Is the earths magnetic field constant throghout?
No, the Earth's Magnetic Field acts just like a BAR Magnetic. It has a North and South Pole and its magnetic lines of its force field are more tightly 'compressed' near the Poles than at the Equator. See the image below for an example, or Google "magnetic field lines".
Where do magnetic field lines cross?
Magnetic field lines don't cross.
Magnetic field lines curve out from one pole and return to the same pole?
No. Magnetic lines curve out from one pole and end up at the opposite pole. Please see the related links for illustrations.
Magnetic field lines curve out from one pole and return to the same pole.?
No. Magnetic lines curve out from one pole and end up at the opposite pole. Please see the related links for illustrations.
What is the direction of magnetic filed lines?
The direction of magnetic field lines are from north to south
How tightly packed the magnetic lines tells us?
The closer the magnetic field lines, the stronger the magnetic force in that area.
What type of magnetic field lines represent uniform magnetic field?
straight parallel lines
What are the lines called that the map out the magnetic field around a magnet?
They are called the magnetic field lines.
