strong
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.
the imaginary lines around the magnet is a magnitic field and strong
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.
It depends on the strength of the magnet.
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 lines of force are closest together at the poles of a bar magnet. As they approach the poles, the magnetic field becomes more concentrated and the lines of force crowd together, displaying greater density.
Iron filings will demonstrate the lines of magnetic force around a magnet.
near both magnetic poles
strength, the number of lines represents how strong the magnet is, this is also sometimes shown by the thickness of the lines.
The configuration of all lines of force around a magnet is called a magnetic field. The magnetic field represents the way in which magnetic forces are distributed in the space surrounding a magnet.
