Given :
Force between two short magnets = f
Distance between magnets = 2l
To Find :
The new force of attraction between the magnets = ?
Solution :
- The force of attraction between magnets is directly proportional to product of theier pole strengths and also inversly proportional to square of the distance between them
- F = Ma×Mb / d²
- When pole strength is tripled and distance id doubled
F₁ = 3Ma×3Mb / (2d)²
F₁ = (9/4) Ma×Mb / d²
F₁ = (9/4) F
The force of attraction between the magnets becomes (9/4) times the original value
