Bar Magnet
A bar magnet is a rectangular object that has a magnetic field. It has two poles: a north pole and a south pole. Like poles repel each other, and unlike poles attract each other.
Table of Contents
- Introduction to Bar Magnet:
A bar magnet is a permanent magnet with a magnetic field that extends around it. It is often made of iron, steel, or other ferromagnetic materials. - Poles of Bar Magnet:
The two ends of a bar magnet are called the north pole and the south pole. The north pole of one magnet repels the north pole of another magnet, while the north pole of one magnet attracts the south pole of another magnet. - Properties of Bar Magnet:
Bar magnets have the following properties: they have two poles, they create a magnetic field, they have a north and south pole, they attract ferromagnetic materials, and they align with Earth's magnetic field. - Magnetic Poles:
Investigating the concept of magnetic poles and their interactions. - Applications of Bar Magnet:
Discovering the various practical uses of bar magnets in everyday life.

Theories and Laws
- Ampère's Circuital Law:
It states that the magnetic field produced by an electric current is proportional to the current flowing through the conductor. - Biot-Savart Law:
This law describes the magnetic field produced by a current-carrying wire at a point in space. - Curie's Law:
This law describes the magnetic susceptibility of a material as it approaches its Curie temperature.
Q/A
Q: What is a bar magnet?
A: A bar magnet is a rectangular object that has a magnetic field with two poles: a north pole and a south pole. Like poles repel each other, and unlike poles attract each other.
Q: How does the strength of the magnetic field change with distance from the magnet?
A: The strength of the magnetic field decreases with increasing distance from the magnet. It follows the inverse square law, meaning the strength is inversely proportional to the square of the distance from the magnet.
Definitions
Magnetic Field:
The region around a magnet where its magnetic influence is felt.
Magnetic Force:
The force exerted by a magnet on another magnet or a magnetic material.
Magnetic Induction:
The process by which a material becomes magnetized in the presence of a magnetic field.
Magnetic Materials:
Materials that can be magnetized and are attracted to magnets.
Magnetic Poles:
The regions on a magnet where the magnetic force is the strongest; a magnet has a north and a south pole.
Curie's Temperature:
The temperature at which a material loses its magnetic properties.
