Question

Difficulty: MediumMagnetism Fundamentals

When a permanent bar magnet is broken into two separate pieces, each piece becomes an independent magnet containing both a north pole and a south pole.

Answer: Answer

Answer

True
In classical electromagnetism and magnetic materials, magnetic monopoles do not exist. Every segment of a magnetized substance retains its aligned atomic domains, ensuring that any severed piece forms a complete magnet with its own distinct north and south poles.

Step-by-Step Solution

1
Analyze the fundamental structure of magnetic materials.
Ferromagnetic materials contain microscopic magnetic domains where atomic magnetic moments are aligned, each acting as a dipole with paired north and south poles.
Understanding the atomic origin of magnetism explains why isolated magnetic poles cannot be produced by mechanical division.
2
Determine the effect of physically separating a magnet into two pieces.
Each broken piece retains aligned internal domains, causing opposite poles to manifest at the newly exposed fractured ends.
Magnetic flux lines must form continuous closed loops, requiring every physical magnet segment to have both a north and a south pole.
