FAQs on Magnetic Field and Electric Currents Video Lecture - NCERT Video Summary: Class 6 to Class 12 (English) - UPSC
| 1. What is the relationship between magnetic field and electric currents? |  |
Ans. The relationship between magnetic field and electric currents is described by Ampere's law, which states that an electric current produces a magnetic field around it. Similarly, a changing magnetic field can induce an electric current in a conductor according to Faraday's law of electromagnetic induction.
| 2. How is the strength of a magnetic field related to the electric current? | |
Ans. The strength of a magnetic field produced by an electric current is directly proportional to the magnitude of the current. This means that increasing the electric current will result in a stronger magnetic field, while decreasing the current will weaken the magnetic field.
| 3. What are some applications of the interaction between magnetic fields and electric currents? | |
Ans. The interaction between magnetic fields and electric currents has various applications in everyday life. Some examples include electric motors, transformers, generators, and MRI machines. These devices utilize the principles of electromagnetism to convert electrical energy into mechanical energy or vice versa.
| 4. How does the direction of an electric current affect the direction of the magnetic field it produces? | |
Ans. The direction of the magnetic field produced by an electric current follows the right-hand rule. If you point your thumb in the direction of the current, the curl of your fingers represents the direction of the magnetic field lines around the current-carrying conductor. Reversing the direction of the current will also reverse the direction of the magnetic field.
| 5. Can an electric current be induced by a stationary magnetic field? | |
Ans. Yes, an electric current can be induced by a stationary magnetic field if there is relative motion between the magnetic field and a conductor. This phenomenon is known as electromagnetic induction and is used in devices such as electric generators and transformers. The change in the magnetic field induces an electric current in the conductor, according to Faraday's law.
