Key Idea.
Section 1
The Distance Rule
Magnetic force is not constant; it is governed by distance. The force is strongest near the poles and weakens rapidly as the distance from the magnet increases.
This implies that a magnet's influence is extremely powerful in its immediate vicinity but diminishes quickly over space.
Section 2
Implications for Interaction
Because force varies with distance, the interaction between magnets changes dynamically as they move.
Expand to review the lesson summary and core properties.
