13. Magnetic Effects of Electric Current

Electro Magnetic induction


Electro Magnetic Induction: The process, by which a changing magnetic field in a conductor induces a current in another conductor, is called electromagnetic induction.

  • The discovery of electromagnetic induction was by made Michael Faraday.
  • The induced current is found to be the highest when the direction of motion of the coil is at right angles to the magnetic field.

Using of a moving magnet can be produced/induced electric current by this discovery of Faradey.

 

Inducing Electric current: 

When we place a moving magnet inside a coil, there produces electric current in the coil's circuit. which can be shown in Galvanometer by deflection of it's needle. The motion of magnet with respect to coil induces a induced potential difference, due to which flows induced electric current in circuit.  

The method to induce electric current in a coil:

(i) we can induce current in a coil either by moving it in a magnetic field. 

(ii) By changing the magnetic field around it.

Which is convenient : 

It is convenient in most situations to move the coil in a magnetic field.

The method to know the direction of such induced current is called "Fleming's Right-hand Rule". 

Galvanometer : Galvanometer is a device which is used to detect induced electric current in a circuit. 

 

Fleming's Right-hand Rule : According to this rule

"Stretch the thumb, forefinger and middle finger of right hand so that
they are perpendicular to each other, If the forefinger indicates the direction of the magnetic field and the thumb shows the direction of motion of conductor, then the middle finger will show the direction of induced current. This simple rule is called Fleming’s right-hand rule.".

Why CBSE Notes Are Important for Exam-Going Students and How to Use Them Effectively

For students preparing for board exams or competitive assessments, CBSE notes have become an indispensable tool. These notes summarize the NCERT textbooks, highlighting key concepts, formulas, definitions, and diagrams in a concise and easy-to-understand format. Unlike lengthy textbooks, CBSE notes allow students to focus on the most important points, saving valuable time during revision.

Importance of CBSE Notes

  • Time-Efficient Revision: With exams approaching, students cannot afford to read entire textbooks multiple times. Notes provide a quick reference for all essential topics.
  • Structured Learning: Notes often organize topics chapter-wise and subject-wise, helping students grasp the flow of the syllabus logically.
  • Better Retention: Well-prepared notes reinforce memory as they include summaries, charts, diagrams, and mnemonics.
  • Exam-Focused Preparation: Many notes highlight probable questions, formulas, and frequently asked questions, enabling targeted preparation.
  • Confidence Boost: Clear, concise notes reduce anxiety, giving students a sense of control over the syllabus.

How to Use CBSE Notes for Best Results

  • Daily Revision: Regularly revise small portions of notes instead of leaving everything for the last days.
  • Highlight Key Points: Use different colors or underlining to emphasize formulas, definitions, and important dates.
  • Practice Alongside Notes: Solve sample papers and previous year questions while referring to notes for quick reference.
  • Create One-Liners: Convert long explanations into one-liner points to remember them easily during exams.
  • Combine With Diagrams and Charts: Visual aids help in remembering complex processes, especially in Science, Geography, and History.
  • Self-Testing: After studying a chapter, close your notes and try recalling all important points to check your understanding.

In conclusion, CBSE notes are not just a revision tool—they are a strategy. When used correctly, they help students cover the syllabus efficiently, improve retention, and approach exams with confidence. For exam-going students, the combination of structured notes, practice, and consistent revision is the key to achieving top results.
