FAQs on Magnetic Effects of electric current Video Lecture - Basic Physics for IIT JAM
| 1. What is the magnetic effect of electric current? |  |
Ans. The magnetic effect of electric current refers to the phenomenon where a current-carrying conductor produces a magnetic field around it. This magnetic field can exert forces on other nearby conductors or magnetic materials.
| 2. How is the magnetic field produced by an electric current? | |
Ans. The magnetic field produced by an electric current is generated due to the movement of charged particles, typically electrons, within a conductor. As the electrons flow, they create a circular magnetic field around the conductor.
| 3. What is the relationship between the strength of the magnetic field and the current in a conductor? | |
Ans. The strength of the magnetic field produced by an electric current is directly proportional to the magnitude of the current flowing through the conductor. This means that as the current increases, the magnetic field strength also increases.
| 4. Can the direction of the magnetic field be changed by reversing the direction of the current? | |
Ans. Yes, the direction of the magnetic field around a current-carrying conductor can be changed by simply reversing the direction of the current flow. The magnetic field lines will then be oriented in the opposite direction.
| 5. How does the magnetic effect of electric current impact everyday life? | |
Ans. The magnetic effect of electric current has numerous practical applications in everyday life. It is used in various devices such as electric motors, generators, transformers, and magnetic storage devices like hard drives. It also enables technologies like electromagnets used in industrial settings and magnetic resonance imaging (MRI) in medical diagnostics.
