← ScienceWhat consequence results when exceeding a magnetron's Curie temperature?
A)Permanent loss of magnetic field✓
B)Increased waveguide power transmission
C)Enhanced electron beam focusing
D)Decreased rate of cavity oscillations
💡 Explanation
Permanent loss of the magnetic field occurs because exceeding the Curie temperature causes the ferromagnetic material to lose its magnetization via thermal agitation disrupting the magnetic domain alignment, therefore the material demagnetizes, rather than oscillate more effectively.
