Questions and Answers
Explain the magnetic effect of electric current and provide examples of its applications in everyday life.
The magnetic effect of electric current refers to the creation of a magnetic field around a current-carrying conductor. This phenomenon is utilized in devices such as electromagnets, electric motors, and transformers.
What is the right-hand rule in the context of the magnetic effect of electric current, and how is it used to determine the direction of the magnetic field around a current-carrying conductor?
The right-hand rule is a technique used to determine the direction of the magnetic field around a current-carrying conductor. By pointing the thumb of the right hand in the direction of the current and curling the fingers, the direction of the magnetic field can be determined.
How does the strength of the magnetic field around a current-carrying conductor change with variations in current intensity and distance from the conductor?
The strength of the magnetic field around a current-carrying conductor is directly proportional to the current intensity and inversely proportional to the distance from the conductor. As the current increases, the magnetic field strength increases, and as the distance from the conductor increases, the magnetic field strength decreases.
