1. The problem statement, all variables and given/known data
I have a hertzian dipole at the origin, generating a signal. Nearby in empty space there is a loop, at a position vector r=(50m)ezz which can detect this signal.

2. Relevant equations
I have the equation B(t) = B0 sin (2*pi*ft)ex which I understand is the signal emitted by the dipole.

I know that along the z-axis (where the dipole is oriented) there is no magnetic field generated by the electric field & that along the equatorial plane it will be maximum.

It should be specified in spherical coordinates & dipole symmetry means the magnitude of the field is independent of radial angle, Ø. The emitted signal is dependent on angle, θ, though.

3. The attempt at a solution
The loop obviously receives the signal, causing a small current to flow in it, hence it can be measured.

How does the orientation of the loop affect the detection of the signal? Could I explain it in terms of the same equation (above)?
I'm not sure . . . . . . . .
