FAQs on NCERT Solutions Class 12 Physics Chapter 5 Magnetism and Matter
1. How many Topics are Present therein Magnetism and Matter?
Ans: Magnetism and matter include various important topics, which are very essential for the students of CBSE board. Maximum questions belong to this chapter; this chapter includes the Magnetic field, Diamagnetism, magnetic analogue, Ferromagnetism, and Electromagnets. It also includes Permanent Magnets, Magnetic Declination and Dip, Magnetism, and Gauss's law, The Earth magnetism, Magnetic intensity, and Various magnetic properties of materials. From this topic, various short types of questions, Long types of questions come in the examination.
2. What do you Mean by the Word Magnetism and Magnetic Fields?
Ans: Magnetism - It generally denotes the combined electromagnetic force. Magnetism is the force that arises between two magnets. It is caused because of the motion of electric charges.
Magnetic Field - The magnetic field is a type of field where magnetic materials, electric charges and electric currents are moving around. So the field, where the particles get magnetically influenced is called the magnetic field. It is generally a vector field where the particles feel a force, perpendicular to its velocity.
3. How does the NCERT Solution of Magnetism and Matter help the Students to Solve Mathematical Problems?
Ans: The NCERT solution Class 12 Chapter 5 'Magnetism and matter' contains theory about magnetic fields, magnetic analogue, earth magnetism, magnetic properties of various materials GAUSS' law, etc. They are discussed briefly, and easily, so all the students can understand the theory. The theoretical knowledge helps the student to solve the mathematical problem and helps to reduce the fear of science, so they score very well in their examination.
4. If Students Have any Additional Doubts, How Does Vedantu Help the Student to Solve Their Queries?
Ans: If the students have additional queries regarding this chapter, they can easily clear their doubts by asking Vedantu's expert. There are also numerous questions present in the app, and by reading thoroughly they can get maximum understanding of the chapter. The experts are always present there to guide the students and help them to score more in the examination.
As the exams are not so far, students do not have a lot of time to prepare all the topics. So, without the best guidance, it is going to be very difficult. Vedantu is one of the best apps when it comes to guidance where every topic is discussed vastly and in-depth. They also help the students to prepare questions and answers, so that students can prepare themselves by attending online live classes. It is going to be a good decision to strengthen one’s understanding of lessons and gain knowledge rewarding question patterns.
5. What are the main topics covered in Chapter 5 - Magnetism And Matter?
Chapter 5 covers topics like magnetic poles and the concept of a magnetic field, magnetic field lines, Earth's magnetism, magnetic properties of materials, and the behaviour of magnetic materials.
6. How can I improve my understanding of the magnetic properties of materials discussed in this chapter?
To improve your understanding of magnetic properties, practice solving numerical problems and experiments related to magnetic materials. You can also conduct simple experiments at home to observe the behaviour of magnetic materials.
7. Is it essential to learn about Earth's magnetism in this chapter?
Yes, understanding Earth's magnetism is crucial in this chapter, as it helps you comprehend the Earth's magnetic field and its significance in navigation and other scientific applications.
8. Does magnetism in affect all matter?
Yes, magnetism affects all matter, but the extent of the effect varies. All materials respond to magnetic fields, though the nature and strength of their response differ. Materials can be classified as diamagnetic, paramagnetic, or ferromagnetic based on their magnetic properties. Diamagnetic materials are weakly repelled by magnetic fields, paramagnetic materials are weakly attracted, and ferromagnetic materials are strongly attracted and can retain their magnetization.
9. What is the cause of magnetism in matter, discussed in Magnetism and Matter NCERT solutions?
The cause of magnetism in matter is the motion of electric charges. At the atomic level, magnetism arises due to the movement of electrons around the nucleus and the spin of electrons on their axes. In ferromagnetic materials, magnetic domains (regions with aligned magnetic moments) contribute to a strong overall magnetic field when aligned.
10. What is the conclusion of Magnetism and Matter class 12 NCERT solutions?
The conclusion of studying Magnetism and Matter class 12 is that magnetic properties are intrinsic to materials and depend on the arrangement and motion of electrons. Understanding these properties helps in the development of various technologies, such as magnetic storage devices, electric motors, and medical imaging equipment. The chapter emphasizes the classification of materials based on their magnetic behaviour and their practical applications in everyday life.
11. What are the units mentioned in Magnetism and Matter NCERT solutions?
The primary units associated with magnetism are:
Magnetic Field (B): Tesla (T) or Gauss (G) (1 T = 10,000 G)
Magnetic Flux (Φ): Weber (Wb)
Magnetic Flux Density (B): Tesla (T)
Magnetic Permeability (μ): Henry per meter (H/m)
Magnetization (M): Ampere per meter (A/m)
Magnetic Field Intensity (H): Ampere per meter (A/m)
12. What is the theory of magnetism in ch 5 physics class 12 NCERT solutions?
The theory of magnetism in Magnetism and Matter NCERT solutions explains how materials respond to magnetic fields due to the alignment of magnetic moments of electrons. The three main types of magnetic materials are:
Diamagnetic: Materials with no net magnetic moment; create an opposing magnetic field and are weakly repelled by magnets.
Paramagnetic: Materials with unpaired electrons that align with the magnetic field, causing weak attraction.
Ferromagnetic: Materials with magnetic domains that align strongly with an external magnetic field, resulting in strong attraction and permanent magnetization.
13. Is magnetism a form of matter?
As per Chapter 5 physics class 12 NCERT solutions, the magnetism is not a form of matter; it is a physical phenomenon that arises from the motion of electric charges. It is an interaction that affects materials, influencing their physical properties and behaviour in the presence of magnetic fields. Magnetism is a fundamental force, much like gravity and electromagnetism, that acts on particles with electric charge.
