Homework Statement
Three vector fields are listed below. Determine whether each of them is electrostatic field or magnetic field.
Homework Equations
F1(x, y, z) = A (9yz ex + xz ey + xy ez)
F2(r,∅,z) = A [(cosx/r)er + (sinx/r) e∅]
F3(r,θ,∅) = Ar2 e(-r/a) er
The Attempt at a Solution
Used matrix to determine the first one
| ex ey ez |
|δ/δx δ/δy δ/δz|
|yz xz xy |
as electrostatic (curl = 0 = -δB/δt) & fine with the how & what defines an electrostatic field
but . . . .
not sure how to determine whether one of these fields is magnetic or not!
Help please.
Thank you.
