1.Two Poles of a Magnet:
A magnet has two poles: a north pole and a south pole. These poles exhibit attractive forces towards each other and repulsive forces when like poles are brought close.
2.Magnet Next to Copper:
When you place a magnet next to copper, typically, copper is not attracted to magnets. Copper is not a ferromagnetic material, so it doesn't exhibit magnetic attraction. However, it may experience an induced magnetic field in the presence of a changing magnetic field.
3.Magnet Next to Iron:
Iron is a ferromagnetic material, and when you place a magnet next to iron, the iron can be attracted to the magnet. The magnetic field induces a temporary magnetism in the iron, causing it to be attracted to the magnet.
4.Relationship Between Distance and Magnetic Attraction:
The magnetic attraction between two magnets or a magnet and a magnetic material decreases as the distance between them increases. The force follows an inverse-square law, meaning that doubling the distance reduces the magnetic force to one-fourth.
5.Examples of Magnetic Force in Everyday Life:
Refrigerator Magnets: Magnets are often used to attach notes or pictures to refrigerators.
Magnetic Door Latch: Many doors have magnetic latches to keep them closed.
Magnetic Compass: A compass needle aligns with the Earth's magnetic field, allowing navigation based on magnetic north.
