Which part of the long bar magnet has the smallest magnetic force? For this question raised by netizens, the following Chinese magnet supplier Courage Magnet will introduce to you the popular science.
The magnetic force in the middle position is small. The two ends of the long bar magnet are S and N grades. The magnetic field distribution is the most dispersed in the middle, because there will be mutual magnetization of the two poles, so the original magnetic force will be weakened, so the middle magnetic force is the smallest.
The magnetic field lines of the magnet start from the top of the N pole and close to the top of the S pole. Because the end has a magnetic aggregation effect, and the middle part is only a magnetic circuit inside the magnet, the end is the strongest and the middle is the weakest.

Is the middle part of the bar magnet not magnetic at all?
That's not true, but according to the principle that the magnetic field lines do not intersect, the distribution of the magnetic field lines in the middle part in space tends to diverge into the air, and there are fewer magnetic field lines close to the surface of the magnet.
