FAQs on Magnetism & Matter Video Lecture - General Awareness for SSC CGL
| 1. What is the relationship between magnetism and matter? |  |
Ans. Magnetism and matter are closely related as matter can be classified into magnetic and non-magnetic materials based on their response to magnetic fields. Magnetism is the property of certain materials to attract or repel other materials, while matter refers to anything that has mass and occupies space.
| 2. How does magnetism affect matter at the atomic level? | |
Ans. At the atomic level, magnetism is primarily caused by the alignment of magnetic moments in the atoms of a material. In magnetic materials, the magnetic moments of the atoms align in a parallel manner, resulting in a net magnetic field. In non-magnetic materials, the magnetic moments are randomly oriented, resulting in no net magnetic field.
| 3. What are the different types of magnetism exhibited by matter? | |
Ans. Matter can exhibit different types of magnetism, including ferromagnetism, paramagnetism, diamagnetism, and antiferromagnetism. Ferromagnetic materials are strongly attracted to magnets, paramagnetic materials are weakly attracted, diamagnetic materials are weakly repelled, and antiferromagnetic materials have alternating magnetic moments canceling each other out.
| 4. How can magnetism be used in everyday life applications related to matter? | |
Ans. Magnetism plays a crucial role in various everyday life applications such as electric motors, generators, MRI machines, magnetic storage devices like hard drives, and magnetic compasses. These applications rely on the interaction between magnetic fields and matter to function effectively.
| 5. Can matter be manipulated to exhibit magnetism artificially? | |
Ans. Yes, matter can be manipulated to exhibit magnetism artificially through processes like magnetization. By applying a magnetic field to a material, its magnetic domains can align in a specific direction, resulting in a net magnetic field. This process is commonly used in the production of magnets and magnetic materials.
