Understanding Induced Current
When a coil moves within a magnetic field, an electromotive force (EMF) is induced, resulting in an induced current. The magnitude of this current depends on the orientation of the motion relative to the magnetic field.
Direction of Motion and Magnetic Field
- The induced current is determined by Faraday's Law of Electromagnetic Induction, which states that the induced EMF in a coil is proportional to the rate of change of magnetic flux through the coil.
- When the direction of motion of the coil is perpendicular to the magnetic field, it experiences the maximum rate of change in magnetic flux.
Why Maximum Induced Current?
- When the coil moves perpendicularly to the magnetic field lines, it cuts through the maximum number of magnetic field lines per unit time.
- This cutting of field lines generates a greater change in magnetic flux, resulting in a stronger induced EMF.
- Thus, the induced current, which is directly related to this EMF, becomes maximum.
Conclusion
In summary, when the motion of the coil is perpendicular to the magnetic field, the induced current reaches its peak value. Thus, the correct answer is option 'B': Maximum. This principle is crucial in applications such as generators, where maximizing induced current is essential for efficient energy conversion.
