Here's why:
* Magnetic field lines: Magnetic field lines originate from the north pole of a magnet and flow into the south pole. The density of these lines represents the strength of the magnetic field.
* Pole concentration: The magnetic field lines are most concentrated at the poles. This means there are more lines packed into a smaller area, resulting in a stronger magnetic field.
* Distance from the magnet: The magnetic field strength decreases as you move further away from the magnet. This means the poles, being the closest points to the maximum magnetic field, will always be the strongest points.
Think of it like a rubber band stretched between two points. The tension, or force, is strongest at the points where the rubber band is attached.
