The orientation of a rotating wire loop in a magnetic field affects the induced voltage in the following ways:
1. If the wire loop is oriented perpendicular to the magnetic field lines, the induced voltage will be at its maximum. This is because the magnetic flux passing through the loop is changing at the fastest rate, resulting in a higher induced voltage.
2. If the wire loop is oriented parallel to the magnetic field lines, the induced voltage will be zero. This is because there is no change in magnetic flux passing through the loop, so no voltage is induced.
3. If the wire loop is oriented at an angle to the magnetic field lines, the induced voltage will be somewhere between zero and the maximum value. The induced voltage will depend on the angle between the wire loop and the magnetic field lines, with the maximum voltage occurring when the loop is perpendicular to the field lines.
In summary, the orientation of a rotating wire loop in a magnetic field affects the induced voltage by changing the rate at which the magnetic flux passing through the loop changes. The induced voltage is highest when the loop is perpendicular to the magnetic field lines and lowest when it is parallel to the field lines.

The induced voltage in a rotating wire loop in a magnetic field is directly proportional to the sine of the angle between the magnetic field vector and the normal vector to the loop.
Mathematical Relationship:
```
ε = -NBAωsin(θ)
```
where:
- ε is the induced voltage
- B is the magnetic field strength
- N is the number of turns in the loop
- A is the area of the loop
- ω is the angular velocity of the loop
- θ is the angle between the magnetic field vector and the normal vector to the loop
Explanation:
When the loop is oriented perpendicular to the magnetic field (θ = 90°), the induced voltage is maximum given by:
```
ε_max = NBAω
```
As the loop rotates away from this perpendicular orientation, the induced voltage decreases. At θ = 0° and θ = 180°, the induced voltage is zero because the magnetic field lines are parallel to the loop surface, and there is no change in magnetic flux.
Implications:
- The maximum voltage is induced when the loop is spinning in a plane perpendicular to the magnetic field.
- The induced voltage goes through a sinusoidal pattern as the loop rotates.
- The orientation of the loop can be adjusted to control the magnitude and direction of the induced voltage.
