There is a repulsive force when north poles (or south poles) of two magnets are brought close together.
If a bar magnet is broken into two halves, we get two similar bar magnets with stronger properties.
The earth behaves as a magnet with the magnetic field pointing approximately from the geographic south to the north.
When a bar magnet is freely suspended, it points in the north-south direction.

Answer 1

The correct answer is If a bar magnet is broken into two halves, we get two similar bar magnets with stronger properties..

Key Points

If a bar magnet is broken into two halves, each half becomes a separate magnet with its own north and south poles.
The magnetic properties of each piece are similar to the original magnet, but not stronger.
Breaking a magnet does not create stronger magnetic properties; the strength of the magnetic field is divided between the two new magnets.
This concept aligns with the principle that magnetic monopoles do not exist; each broken piece still retains a dipole nature.

Additional Information

Magnetic Poles
- Magnets have two poles: north and south.
- Like poles repel each other, while unlike poles attract.
Magnetic Field of Earth
- The Earth’s magnetic field is similar to that produced by a giant bar magnet.
- The magnetic field lines extend from the geographic south pole to the north pole.
Suspension of Magnets
- When freely suspended, a magnet aligns itself along the north-south direction due to the Earth’s magnetic field.
- This property is utilized in the functioning of magnetic compasses.
Magnetic Monopoles
- The concept of magnetic monopoles (isolated north or south poles) does not exist in classical physics.
- Every broken piece of a magnet retains both a north and south pole.
