Homework Statement
State whether the following arbitary fields can describe either a magnetic field, a magnetostatic field, neither, or both. In each case justify your answer:
i) R(r) = R0 (x2,y2,z2)
ii) S(r) = S0 (x, -z, y)
iii) T(r) = T0 (-z, 0, x)
Homework Equations
div B= 0
The Attempt at a Solution
i) div R = R0 (2x, 2y, 2z)
Not a magnetic field as div B [itex]\neq[/itex] 0
ii) div S = S0 (1,0,0)
Not a magnetic field as div B [itex]\neq[/itex] 0
iii) div T = T0 (0,0,0)
Can represent a magnetic field as div B = 0
I don't know if the above is correct for the magnetic field and I don't have a clue where to start to establish a decision about them being a magnetostatic field or not!
