A magnetic Field
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
because the magnet causes particles called electrons in the atoms of the nail to align along the magnet's lines of force. The atoms with aligned electrons then act like tiny bar magnets themselves.
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!
the imaginary lines around the magnet is a magnitic field and strong
magnetic lines of force
Iron filings will demonstrate the lines of magnetic force around a magnet.
Magnetic Field!
a magnet with many lines of force is STRONG
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.
The magnetic field surrounds the magnet. The lines of magnetic force repel each other, ultimately forming a sphere of decreasing strength.
Magnetic flux
Faraday, proposed lines of flux and lines of force.
They are called the magnetic field lines.
They are called the magnetic field lines.
The volume surrounding a magnet will be filled with the lines of magnetic force. Since these are similarly polarized, they repel each other - eventually creating a sphere at a sufficiently large distance. This sphere is the magnetic field of that magnet.
