An electric current flowing through a metallic conductor generates a magnetic field around it. This phenomenon is a fundamental principle of electromagnetism.
Correct Answer
The correct option is (C) Magnetic field.
Explanation
When electrons move through a conductor, they create a magnetic field due to their charge and motion. This effect is utilized in various applications, such as electric motors and transformers.
Key Points
- Electric current is the flow of electric charge.
- Magnetic fields are produced by moving charges.
- This principle is essential in many electrical devices.
