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 of force around a magnet are called magnetic field lines. These lines represent the direction in which a north magnetic pole will tend to move if placed in the field.
the imaginary lines around the magnet is a magnitic field and strong
Imaginary lines of force around a magnet are called magnetic field lines. They represent the direction and strength of the magnetic field. These lines provide a visual way to understand how magnetic fields behave and interact with other magnets or magnetic materials.
Iron filings will demonstrate the lines of magnetic force around a magnet.
The area around a magnet that has the force of magnetism is called the magnetic field. The magnetic field is the region where the magnetic force produced by the magnet can influence other objects or materials.
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.
Magnetic flux
Iron filings are commonly used to demonstrate the lines of magnetic force around a magnet. When sprinkled around a magnet, the filings align themselves along the magnetic field lines, making the field visible.
Faraday, proposed lines of flux and lines of force.
They are called the magnetic field lines.
They are called the magnetic field lines.
A magnet with many lines of force refers to a strong magnetic field that is densely packed with magnetic field lines. These field lines represent the pathways along which the magnetic force acts, flowing from the magnet's north pole to its south pole. The density of these lines of force indicates the strength of the magnet's magnetic field.
