Class VI Science (Curiosity) Book Solution with Key Notes/Points © kvsecontent.com Chapter 4 - Exploring Magnets Key Notes Magnets- Objects that attract materials like iron, cobalt, and nickel. Magnets have the ability to pull or attract certain metals. They are used in various applications, from compasses to electronics. Magnetic and Non-Magnetic Materials- Magnetic Materials- These are materials that are attracted to magnets (e.g., iron, nickel, cobalt). Non-Magnetic Materials- These materials are not attracted to magnets (e.g., plastic, wood, glass). Magnetic materials have properties that allow them to be influenced by a magnet's force, while non- magnetic materials do not interact with magnets. Poles of a Magnet- Every magnet has two poles, North (N) and South (S). The poles are where the magnetic forces are strongest. The North pole of one magnet will attract the South pole of another, while like poles (N-N or S-S) will repel each other. Attraction and Repulsion Attraction Unlike poles (North-South) attract each other. Repulsion Like poles (North-North or South-South) repel each other. This is a fundamental property of magnets. When opposite poles are brought together, they pull towards each other, while similar poles push away from one another. Magnetic Compass- A device that uses a magnet (usually a magnetic needle) to find directions by pointing towards Earth's magnetic North. The compass needle aligns itself along the North-South direction because the Earth itself behaves like a giant magnet. This property helps people find directions. Lodestone- A naturally occurring magnetic rock. Lodestones are a type of magnet that was discovered in ancient times. Sailors used them for navigation before the invention of modern compasses. Magnetic Field- The area around a magnet where its magnetic force is effective.
