Which statement is true about magnetic poles?

• A. Like poles attract
• B. Unlike poles attract
• C. Like poles repel
• D. Unlike poles repel

Answer: (B)

Opposite magnetic poles attract because of how magnetic field lines connect north to south. The north pole of one magnet acts as a source of field lines and the south pole of another acts as a sink. When these opposite ends face each other, the field lines form a continuous path between the magnets, which creates an attractive force and lowers the system’s magnetic potential energy. That intuitive idea—like ends repel and opposite ends pull together—captures why unlike poles come together. If the same poles are brought near, the field lines push apart, producing a repulsive force. So the statement that unlike poles attract reflects the fundamental interaction of magnetic poles.
