FAQs on NCERT Solutions for Class 10 Science Hindi Chapter 13 Magnetic Effects of Electric Current
1. What key topics are covered in the NCERT Solutions for Class 10 Science Chapter 13, Magnetic Effects of Electric Current?
The solutions provide step-by-step answers for all topics in the chapter as per the CBSE 2025-26 syllabus. This includes:
- Magnetic field and field lines
- Magnetic field due to a current-carrying conductor (straight wire, circular loop, and solenoid)
- Force on a current-carrying conductor in a magnetic field (including Fleming's Left-Hand Rule)
- Electric Motor
- Electromagnetic induction (including Fleming's Right-Hand Rule)
- Electric Generator
- Domestic electric circuits, including safety measures like earthing and fuses.
2. How do these NCERT Solutions explain the working principle of an electric motor?
The solutions provide a detailed, step-by-step explanation of the electric motor's function. It clarifies the underlying principle: a current-carrying conductor placed in a magnetic field experiences a force. The solution explains the role of each component like the armature coil, permanent magnets, split-ring commutator, and brushes, and shows how to apply Fleming's Left-Hand Rule to determine the direction of rotation.
3. What is the correct method to determine the direction of a magnetic field around a straight current-carrying conductor, according to the NCERT solutions?
The correct method explained in the solutions is the Right-Hand Thumb Rule. The solution guides you to imagine holding the conductor in your right hand with your thumb pointing in the direction of the current. The direction in which your fingers curl around the conductor gives the direction of the magnetic field lines.
4. How do the solutions clarify the difference between an AC generator and a DC generator?
The NCERT solutions clearly distinguish between AC and DC generators based on their construction and output. The key difference highlighted is the type of commutator used: an AC generator uses two slip rings, while a DC generator uses a split-ring commutator. This difference is what allows the DC generator to produce a unidirectional current.
5. Why is it important to follow the step-by-step problem-solving approach shown in these solutions for exam questions?
Following the step-by-step method provided in the NCERT solutions is crucial for exams because it ensures clarity and fetches full marks. For complex topics like the electric motor or generator, this approach helps you explain the principle, construction, and working in a logical sequence, which is exactly what CBSE examiners look for. It also prevents you from missing key points.
6. How do the solutions for Chapter 13 help tackle application-based questions, such as the one involving an electron beam in a magnetic field?
The solutions break down complex application-based problems into simple steps. For the electron beam question, the solution first identifies the direction of conventional current (opposite to electron flow) and then applies Fleming's Left-Hand Rule to determine the direction of force and deflection. This methodological approach helps you apply theoretical concepts to practical scenarios, a key skill for scoring well.
7. How are the concepts of short-circuiting and overloading explained in the NCERT Solutions?
The solutions define a short circuit as a situation where the live wire and the neutral wire come into direct contact, causing a sudden and large surge in current. Overloading is explained as drawing more current than the circuit can safely handle. The solutions emphasize that both situations can lead to overheating and fire, highlighting the importance of safety devices like fuses.
8. What is the function of an earth wire, and why is it necessary for metallic appliances, as explained in the NCERT solutions?
As detailed in the solutions, the earth wire is a safety measure. It provides a low-resistance path for current to flow to the ground in case of accidental leakage onto the metallic body of an appliance (like a refrigerator or toaster). This prevents the user from receiving a severe electric shock, making it a critical safety feature for appliances with metal casings.
9. Beyond just providing answers, how do these solutions clarify the concept of electromagnetic induction (EMI)?
The solutions for Chapter 13 explain EMI not just as a definition but through practical examples from the textbook, like the coil-and-magnet experiment. They show how a current is induced in a coil only when there is relative motion between the coil and a magnetic field. This focus on the "why" and "how" helps build a stronger conceptual understanding beyond rote memorization.
