Understanding the Force on a Current-Carrying Conductor
When a conductor carrying an electric current is placed in a magnetic field, it experiences a force. The magnitude of this force can be analyzed using the formula:
- F = BIL sin(θ)
Where:
- F = Force on the conductor
- B = Magnetic field strength
- I = Current flowing through the conductor
- L = Length of the conductor
- θ = Angle between the conductor and the magnetic field (90 degrees when at right angles)
Impact of Increasing the Length of the Conductor
When the length of the conductor (L) increases while keeping the current (I) and magnetic field strength (B) constant, the following occurs:
- Direct Proportionality: The formula shows that the force (F) is directly proportional to the length of the conductor (L). Thus, if L increases, the force (F) also increases.
- Constant Parameters: Since the current (I) and the magnetic field (B) are unchanged, the only variable that affects the force is the length of the conductor.
Conclusion
In summary, when the length of a current-carrying conductor placed at right angles to a magnetic field increases, the force exerted on it increases. Therefore, the correct answer to the question is option 'A' - the force increases. This relationship illustrates the significant role of conductor length in electromagnetic interactions and is fundamental in electrical engineering applications such as motors and generators.
