FAQs on NCERT Solutions For Class 10 Science Chapter 13 Magnetic Effects of Electric Current in Hindi - 2025-26
1. What key concepts from Chapter 13 are explained in Vedantu's NCERT Solutions?
Our NCERT Solutions for Class 10 Science Chapter 13 provide step-by-step explanations for all topics as per the CBSE 2025-26 syllabus. Key concepts covered include:
- Magnetic field and field lines
- The magnetic field produced by a current-carrying conductor (straight, circular loop, solenoid)
- Right-Hand Thumb Rule
- Force on a current-carrying conductor in a magnetic field
- Fleming's Left-Hand Rule and its application in the electric motor
- The principle of electromagnetic induction
- Fleming's Right-Hand Rule and its application in the electric generator
- Domestic electric circuits, including overloading, short-circuiting, and safety measures like fuses and earthing.
2. What is the step-by-step method shown in the solutions to explain the working of an electric motor?
The solutions explain the electric motor's function by breaking it down into a logical sequence. First, they state the principle: a current-carrying coil in a magnetic field experiences a force causing it to rotate. Then, using Fleming's Left-Hand Rule, the solutions show how to determine the direction of force on each arm of the coil. Finally, they explain the crucial role of the split-ring commutator in reversing the current direction to ensure continuous rotation.
3. How do the NCERT Solutions explain the Right-Hand Thumb Rule for a straight conductor?
The solutions provide a clear, methodical guide to applying the Right-Hand Thumb Rule. You are instructed to imagine holding a straight current-carrying wire in your right hand. If your thumb points in the direction of the conventional current, the direction in which your fingers wrap around the wire indicates the direction of the concentric magnetic field lines.
4. How do the solutions for Chapter 13 help solve application-based questions, like finding the force on an electron in a magnetic field?
The solutions teach a systematic approach for such problems. For an electron moving in a magnetic field, the first critical step shown is to identify the direction of conventional current, which is opposite to the flow of electrons. Once this is established, you can correctly apply Fleming's Left-Hand Rule (using the direction of conventional current, magnetic field, and force) to determine the direction of deflection, a common area for mistakes.
5. According to the NCERT Solutions, what is the main construction difference that leads to the different outputs of AC and DC generators?
The solutions pinpoint the key component responsible for the difference: the commutator. An AC generator uses two continuous slip rings, which allows the direction of the induced current to reverse every half rotation, producing an alternating current. A DC generator, however, uses a split-ring commutator, which reverses the connection to the external circuit every half rotation, ensuring the output current always flows in a single direction (unidirectional).
6. How do the solutions explain the safety function of an earth wire in domestic circuits?
As detailed in the solutions, the earth wire is a critical safety feature for appliances with metallic bodies. It provides a low-resistance path for any leaked current from the live wire to the appliance's casing to flow directly to the ground. This causes a massive surge in current, which trips the fuse and cuts off the electricity supply, preventing the user from receiving a potentially fatal electric shock.
7. Why is it crucial to follow the problem-solving steps from the NCERT Solutions in the CBSE board exam?
Following the structured, step-by-step method shown in the NCERT Solutions is vital for securing full marks in CBSE exams. For complex devices like motors and generators, this method ensures you cover all key points—principle, construction, working, and the relevant rule—in a logical order. This clarity not only prevents you from missing steps but also aligns perfectly with the marking scheme used by CBSE examiners.
8. Why is it incorrect to use the Right-Hand Thumb Rule to find the direction of force on a conductor, as per the principles in Chapter 13?
This is a common point of confusion that the NCERT solutions implicitly clarify. The Right-Hand Thumb Rule is used only to find the direction of the magnetic field produced by a current. To find the direction of the force (or motion) experienced by a current-carrying conductor placed in an external magnetic field, you must use Fleming's Left-Hand Rule. Using the wrong rule for the situation will lead to an incorrect answer.
9. How do these NCERT solutions go beyond just giving answers to build a deeper understanding of electromagnetic induction (EMI)?
The solutions foster a deeper understanding of EMI by explaining the 'how' and 'why' behind it. Instead of just stating the definition, they explain through textbook examples (like the magnet and coil experiment) that a current is induced only when there is relative motion between the conductor and the magnetic field. This focus on the underlying condition for induction helps you move from rote learning to true conceptual clarity, which is essential for tackling HOTS questions.
10. Are these NCERT Solutions for Magnetic Effects of Electric Current updated for the 2025-26 CBSE session?
Yes, all the questions and answers provided in our NCERT Solutions for Class 10 Science Chapter 13 are meticulously prepared and verified by subject matter experts to be fully aligned with the latest CBSE syllabus and NCERT textbook for the 2025-26 academic year. This ensures you are studying the most relevant and accurate material for your exams.
