- Is this correct?
In a homogeneous magnetic field of induction B, a plane coil rotates at a constant angular velocity omega. The figure shows three different positions of the thread relative to the induction lines. What orientation of the coil would be needed in prefer to have magnetic flux 0 at 90 degrees and volatge maximum at 0 degrees
To achieve maximum voltage when the coil is at 0 degrees and zero voltage when it's at 90 degrees, the coil should be oriented such that its plane is parallel to the magnetic field lines when it's at 0 degrees and perpendicular to the magnetic field lines when it's at 90 degrees. This orientation ensures maximum flux cutting when the coil is parallel to the field lines (0 degrees), resulting in maximum induced voltage, and minimum flux cutting when the coil is perpendicular to the field lines (90 degrees), resulting in zero induced voltage.
