Magnetic fields are bascially lines of force caused by magnetic poles. It is invisible, but you can track how the field lines are formed doing a small experiment. Spread some iron fillings on a tray. Then bring a magnet up close to the iron fillings but not too close. You can observe that the iron fillings move into the field lines of the magnet that you brought up close. That's a miniature of a magnetic field. The earth's magnetic field is much bigger.

Compare the strength of the magnetic field near one pole of a bar magnet with the strength of the magnetic field farther away from the magnet?
Magnetic field lines are stronger when closer together.
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.
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.
Imaginary lines of force around a magnet?
Magnetic Field!
Why does a compass spin when it is placed next to a magnet?
A compass needle is a small magnet itself. When it is placed next to a larger magnet, the magnetic field of the larger magnet interacts with the magnetic field of the compass needle. This interaction causes the compass needle to align with the magnetic field of the larger magnet, causing it to spin and point in the direction of the magnetic field lines.
The number of lines of force in a magnetic field depends on the what of the magnet?
It depends on the strength of the magnet.
Compare the strength of the magnetic field near one pole of a bar magnet with the strength of the magnetic field farther away from the magnet?
Magnetic field lines are stronger when closer together.
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.
The number of lines of force in a magnetic field depends on the blank of the magnet?
strength, the number of lines represents how strong the magnet is, this is also sometimes shown by the thickness of the lines.
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.
How do you determine the strength of a magnet using lines of forces?
The closer the lines of force are together, the stronger the magnetic field it represents.
What are the lines called that the map out the magnetic field around a magnet?
They are called the magnetic field lines.
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!
Are the lines that map out the magnetic field around a magnet?
no
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 are lines called that map out the magnets field around the magnet?
They are called the magnetic field lines.
What does the relative density of lines of a magnetic field tell us about the strength of the field?
The closer the lines the stronger the magnetic field.
