FAQs on Electromagnetic Induction Class 12 Notes: CBSE Physics Chapter 6
1. What is Motional Electromotive Force?
An EMF generated by the movement of the conductor (a rectangular coil) towards the magnetic field ‘B’ is a motional electromotive force. Its equation is given by:
E = - vLB
This equation remains valid as long as the velocity (v), field (B), and length (L) are mutually perpendicular to each other. The negative sign points to Lenz’s law.
2. Write Applications of Electromagnetic Induction.
The phenomenon of EMI is the basis of working for the following devices:
Power Generators,
Dynamos,
Transformers
3. How can I Score Well in the Class 12 Physics Exam?
Class 12 Physics demands practice. For having a good hold of concepts, it is necessary to follow the tips mentioned below.
Go through the latest CBSE Syllabus.
Stick to study plan, and hierarchically prepare your topics.
Revise the topics daily.
Solve model papers to brush up your numerical solving ability (available on Vedantu with solutions).
Opt for solved PYQP to stay updated with the level of questions asked and the weightage of each topic.
4. What is the Weightage of Numerical Type Questions in the Class 12 Physics Exam?
There is no particular weightage for the numerical type questions of any unit in the Class 12 Physics exam. The weightage of numerical type questions from some topics range between 10-15 marks.
5. What is electromagnetic induction in reference to Chapter 6 Class 12th?
Electromagnetic Induction refers to the process of generating current or inducing emf due to a changing flux. When a changing current passes through a closed coil, a varying magnetic flux begins to develop inside of it which in turn induces an emf in the coil. This leads to the generation of induced current inside the closed coil. Therefore, this phenomenon of current or an indices emf due to the frequent change of the flux is known as Electromagnetic Induction.
6. What are the important topics for Class 12 Physics apart from Chapter 6?
As your final exams might be around the corner, you must be wondering what topics you must focus on. You should know that each chapter is important, however, there are a few important topics within each chapter. Some of the important topics include Coulomb's Law, potential due to electric dipole, Ohm's Law, magnetic force on the current-carrying wire, axial magnetic field of a bar magnet on the solenoid, magnetic Flux, RC, LC, LR, and LCR circuits, displacement current, image formation, and many more.
7. How to score more than 90% in class 12th CBSE in Chapter 6?
The board question papers generally rely on NCERT textbooks and the concepts it covers. Therefore, studying from NCERT textbooks and solutions from Vedantu can ensure that you will score good marks in your board exams. However, apart from NCERT textbooks, you may also be required to go through other reference books as well. To score more than 90% marks in your CBSE Class 12 Boards exams, apart from questions available in the book, you need to solve the questions of all the previous year’s question papers available.
8. What is Eddy's current class 12th?
Eddy's current refers to induced currents that are available in a body of a conductor. These currents are generated through a change of magnetic flux. This current was discovered by a famous scientist named Foucault. Hence, Eddy's current is also known as Foucault's current after the scientist who discovered it. An example of Eddy's current includes a metal plate that consists of a magnetic field presence. In such a case, Eddy's current is inducted into the metal plate.
9. What is Faraday's first law?
Faraday's first law of electromagnetic induction in physics refers to the fundamental law of induction. This law states that varying magnetic fields can generate electric currents when induced in closed coils. These induced electric magnetic fields can last for a long time as long as the magnetic flux changes frequently. Therefore, the chemical change that is produced in the electrode-electrolyte by the current is said to be proportional to the total quality of electricity that is used.
