Are the magnetic field vector- or scalar fields?

Answer:
Both, E=Es + Ev = cB therefore, B= Es/c + Ev/c = Bs + Bv.

The electric and magnetic fields are quaternion fields consisting of a scalar field and a vector field.

Contemporary Physics has not realized this yet. Correct Relativity Theory is a manifestation of quaternion fields, consisting of a scalar field and three vector fields. This shows up in the Energy Momentum four vector, E= Es +cmV.

Actually the Lorentz Force is both scalar and vector: F=qvB = - qv.B + qvxB
it makes no sense consider only qvxB and to ignore qv.B.
