Direction of the induced current

Click For Summary
SUMMARY

The direction of the induced current in a rotating wire within a constant magnetic field is determined by the orientation of the area vector relative to the magnetic field. If the area vector is parallel to the magnetic field, the induced current flows in one direction; if anti-parallel, it flows in the opposite direction. This phenomenon is governed by Lenz's Law, which states that the induced current will flow in a direction that opposes the change in magnetic flux. Understanding these principles is crucial for applications in electromagnetism.

If there is a rotating wire in a constant magnetic field what is the direction of the induced current ?
The problem is the direction of the area vector which is arbitrary, if it is parallel to the magnetic field the current will flow in a direction, if it is anti-parallel it will flow in the opposite direction.
What is wrong ?
