Why do we need to bring two magnets close to see the magnetic effect between them?

Bringing two magnets close together allows us to observe the magnetic effects due to their interaction, which is governed by the magnetic fields they generate. Each magnet has areas of magnetic influence called poles (north and south), and when they are near each other, their fields interact, resulting in attraction or repulsion. This interaction illustrates fundamental principles of magnetism and helps us understand how magnetic forces operate in various applications. Without proximity, the magnetic fields would not significantly affect each other, making their effects undetectable.
