FAQs on Magnetic Effect of Current Video Lecture - Science Class 10

1. What is the magnetic effect of current?
Ans. The magnetic effect of current refers to the phenomenon where a current-carrying conductor produces a magnetic field around it. This magnetic field can exert a force on other nearby magnets or current-carrying conductors.
2. How does the magnetic effect of current work?
Ans. The magnetic effect of current is based on Ampere's law, which states that a magnetic field is produced around a current-carrying conductor. This magnetic field forms concentric circles around the conductor, and the direction of the magnetic field can be determined using the right-hand rule.
3. What are the applications of the magnetic effect of current?
Ans. The magnetic effect of current has various practical applications. Some of the common applications include electric motors, generators, transformers, magnetic resonance imaging (MRI) machines, and magnetic levitation systems.
4. What is the difference between the magnetic effect of current and the electric effect of magnetism?
Ans. The magnetic effect of current refers to the production of a magnetic field by a current-carrying conductor, while the electric effect of magnetism refers to the production of an electric current by a changing magnetic field. These two phenomena are interconnected and form the basis of electromagnetism.
5. How can the magnetic effect of current be increased?
Ans. The magnetic effect of current can be increased by increasing the current flowing through the conductor, increasing the number of turns in a coil, or using a material with a higher magnetic permeability. Additionally, placing the conductor in the proximity of a magnet can also enhance the magnetic effect.
