Answer:
Introduction:
When a wire loop is rotated in a magnetic field, an electromotive force (EMF) is induced in the wire loop. The frequency of change in the direction of the induced EMF depends on the number of times the wire loop rotates in the magnetic field.
Explanation:
The frequency of change in the direction of the induced EMF is equal to the number of times the wire loop rotates in the magnetic field. Therefore, the frequency of change in the direction of the induced EMF can be calculated by dividing the number of rotations per second by the number of rotations per revolution.
The given problem states that the frequency of change in the direction of the induced EMF is n times per revolution. Therefore, the frequency of change in the direction of the induced EMF can be calculated as follows:
Frequency of change in the direction of the induced EMF = (number of rotations per second) / (number of rotations per revolution)
n = (number of rotations per second) / 1
Number of rotations per second = n
Therefore, the frequency of change in the direction of the induced EMF is equal to the number of rotations per second.
The problem states that the frequency of change in the direction of the induced EMF is n times per revolution. Therefore, the number of rotations per revolution can be calculated as follows:
Number of rotations per revolution = 1 / n
Now, we can determine the answer to the problem by matching the given frequency of change in the direction of the induced EMF with the corresponding number of rotations per revolution.
- If the frequency of change in the direction of the induced EMF is 6 times per revolution, then the number of rotations per revolution is 1/6. Therefore, the answer is option 1.
- If the frequency of change in the direction of the induced EMF is once per revolution, then the number of rotations per revolution is 1/1. Therefore, the answer is option 2.
- If the frequency of change in the direction of the induced EMF is twice per revolution, then the number of rotations per revolution is 1/2. Therefore, the answer is option 3.
- If the frequency of change in the direction of the induced EMF is four times per revolution, then the number of rotations per revolution is 1/4. Therefore, the answer is option 4.
Conclusion:
In conclusion, the frequency of change in the direction of the induced EMF in a wire loop rotated in a magnetic field is equal to the number of rotations per second. The number of rotations per revolution can be calculated by dividing 1 by the frequency of change in the direction of the induced EMF. The answer to the problem can be determined by matching the given frequency of change in the direction of the induced EMF with the corresponding number of rotations per revolution.

3) twice per revolution Flux of the magnetic field through the loop is= Br2 cos wtWhere = angle the normal makes with the portion of the loop induced emf.= wBr2sinwt.These is zero when wt = n i.e.,When = 0, , 2.... = 0, , 2.... etc.So, the induced emf direction every half rotation.Hence direction changes twice per revolution.
