WebThe magnetic field expressed as a line is called a ‘magnetic force line.’. When the magnetic field is strong, the magnetic force lines appear dense, and where the magnetic field is weak, the magnetic force lines appear sparse. In a bar magnet, the closer it is to the magnet’s N and S poles, the denser the magnetic force line. WebA magnetic field is a picture that we use as a tool to describe how the magnetic force is distributed in the space around and within something magnetic.

BTW, magnets have a saturation and if you search for images where iron shavings show the field lines you will see that they start and end not only on the plane ends of the bar magnet. WebIntroduction Magnetic fields. Magnetic fields are vector quantities characterized by both strength and direction. The strength of a magnetic field is measured in units of tesla in the SI units, and in gauss in the cgs … flags waving in the wind
