As we know, Earth has its own magnetic field, and the core of the Earth’s generates its own magnetic field. The effect of magnetism is felt where the magnetic field is present. The magnetic field, electric field and light are the fundamental forces that bind the universe. Electromagnetism plays an important role in the development of various concepts of science. Hence it is one of the essential topics to be known by the students who study science. Electromagnetic induction class 12 is one of the chapters that introduce the phenomenon of the electromagnetic effect being introduced for students.
To know the effect of magnetism, the cause of magnetism and also to learn about the action of magnetic force with various matters, chapters like magnetism and matter is also introduced for the students. The study material for magnetism and matter class 12 notes is available online. In this article, let us know the concepts covered in the Electromagnetic induction class 12 chapter and also let’s get an idea about the magnetism and matter class 12 notes.
Electromagnetic Induction Unit
This chapter mainly focuses on the conservation of energy, experiments of Faraday and Henry, Lenz’s law, and Faraday’s Law of induction. To completely understand the concept of electromagnetism, it is recommended to solve the exercise questions and problems. It is one of the key chapters to expect the questions in board examinations or any competitive examinations. It is also necessary to keep in mind the NCERT syllabus and study accordingly. It is also a good idea to know a bit about great scientists behind electromagnetism like Faraday and Henry.
Have a detailed observation on the experimental set-up, procedure and the results in the experiments mentioned. Have clarity on various formulas and use the formulas accordingly. The practice problems should be practiced till you get the expertise. Know about emotional electromotive force, eddy currents, inductance and AC generators too. Additional problems also help to gain more knowledge and confidence.
Magnetism And Matter
It is also an important chapter in the point of examinations. There are many online resources available for reference. But choose the proper content magnetism and matter class 12 notes. Select the notes according to the NCERT syllabus for reference. Magnetism and matter class 12 chapter deals with properties of the magnet, Gauss law, magnetic field lines, magnetic dipole moment, diamagnetism, paramagnetism, ferromagnetism, and also the diagram in detail about magnetic field lines. Also, topics like Lorentz law, magnetic field and force, moving coil galvanometer, Biot Savart’s law, solenoid, and bar magnets are covered in this chapter. The sub-topic like Earth’s magnetism elaborates the magnetic properties of the Earth and explains the various components of the magnetic field. Learn how the magnetic materials are classified depending on their properties. Solving practise problems lets the students learn and apply the concepts in a better way. Since notes provide the explanation for the questions and help the students to get the detailed way of solving the problems, it is the best way to opt for the good notes as a guide.
