How does length and thickness of magnet affect the strength of magnetic field?

The strength of a magnetic field is influenced by both the length and thickness of a magnet. Generally, a longer magnet can produce a more uniform and stronger magnetic field over a larger area, as its magnetic poles are spaced farther apart. Thickness also plays a role; thicker magnets can generate a stronger magnetic field due to increased magnetic material, which enhances the overall magnetic flux. However, the specific material and magnetization process also significantly affect the field strength.
