Question

which pair of magnets will repel each other the greatest force? a. diagram of two magnets with s and n ends b. diagram of two magnets with n and s ends c. diagram of two magnets with s and n, and n and s ends d. diagram of two magnets with n and s, and n and s ends

Explanation:

Step1: Identify repelling pole pairs

Magnetic repulsion occurs between like poles (N-N or S-S). First, check each option:

• A: N (first magnet) faces S (second magnet) → attraction, not repulsion.
• B: S (first magnet) faces S (second magnet) → repulsion.
• C: N (first magnet) faces N (second magnet) → repulsion.
• D: N (first magnet) faces N (second magnet) → repulsion.

Step2: Compare pole alignment strength

The magnetic force is strongest when the poles are fully aligned and facing each other directly. In option B, the flat sides of the magnets (with full pole surfaces) are facing each other, maximizing the contact area of like poles, which creates a stronger repulsive force than the partial alignment in C and D.
