Illustrate the demerits of ultrasonic magnetostriction method.
Limitations of ultrasonic magnetostriction method:
a. This can produce frequencies up to 3 MHz simply.
b. This is not possible to acquire a constant single frequency, since rod depends onto temperature and the degree of magnetization.
c. When the frequency is inversely proportional to the length of the vibrating rod, to raise the frequency, the length of the rod must be decreased that is practically not possible.
