Answer:
Explanation:
Assuming you are asking about the frequency of oscillation of the needle: The frequency of oscillation of the needle will be the same as the frequency of the external magnetic field. If the external magnetic field is applied at a frequency of 10 hertz, then the frequency of oscillation of the needle will be 10 hertz.
