FAQs on Magnetic and Non - Magnetic Materials Video Lecture - Class 6

1. What are magnetic materials?
Ans. Magnetic materials are substances that are attracted to magnets or can be magnetized. They possess magnetic properties due to the alignment of their atomic or molecular structure.
2. Give examples of magnetic materials.
Ans. Some examples of magnetic materials include iron, nickel, cobalt, and their alloys. Other materials like steel, magnetite, and lodestone also exhibit magnetic properties.
3. What are non-magnetic materials?
Ans. Non-magnetic materials are substances that are not attracted to magnets and do not possess magnetic properties. Their atomic or molecular structure does not allow for magnetic alignment.
4. Provide examples of non-magnetic materials.
Ans. Examples of non-magnetic materials include wood, plastic, rubber, glass, aluminum, copper, and most non-metallic substances. These materials do not exhibit any attraction or repulsion towards magnets.
5. Can materials change their magnetic properties?
Ans. Yes, materials can change their magnetic properties. Some materials can be magnetized, meaning they can be turned into magnets by aligning their atomic or molecular structure. On the other hand, certain materials can lose their magnetism over time due to factors such as heat or exposure to strong external magnetic fields.
