Yes the Phi indicates a unit vector,
so since we're working in the direction of phi, the E x Curl is
|r ... theta ...phi |
|d/dr...[(1/r*sin(phi))*d/dtheta] ...[(1/r) d/dphi] |
|0... 0 ...E |...
Homework Statement
The electric field of a spherical electromagnetic wave in vacuum can be written in the form of:
E(r,θ,phi)= A(sin(θ)/r)*[cos(kr-ωt)-(1/kr)sin(kr-ωt)]phi
Show that E is consistent with ALL of Maxwell's equations in vacuum and find the associated magnetic field...
