Week 10 Ferromagnetism, Uniformly Magnetised Sphere and Hysteresis Flashcards
1
Q
what is true of H & B inside a ferromagnet
A
H & B move in opposite direction to each other inside a ferromagnet
2
Q
what is the best way to consider H
A
as grad of something else
H = -∇ψ
3
Q
what is the monochromatic plane wave equation for electrics
A
E = E0 exp[i(kr - ωt)]
4
Q
what is always true of E, B and k(direction of propagation)
A
They are mutually orthogonal
