Question

The energy density of the magnetic crystal is Uk = K sin2 θ. Find the resonance frequency in a magnetic field. a) ωo = (Bo + BA) b) ωo = r(Bo + BA) c) ωo = rBo d) ωo = r2(Bo + BA)

Answer 1

Answer:

Maximum Electric field E=(B)(c)

E0=(3×10−5)c(−j^)

E1=(2×10−6)c(−i^)

Maximum force

Fnet=qE=qc(3×10−5j^−2×10−6i^)F0max=10−4×3×108(3×10−5)2+(2×10−6)2
