A plane electromagnetic wave traveling in the positive direction of an x axis in vacuum has components
Question:
A plane electromagnetic wave traveling in the positive direction of an x axis in vacuum has components Ex = Ey = 0 and E z = (2.0 Vim) cos [(π x 1015 s-1) (t – x/c)].
(a) What is the amplitude of the magnetic field component?
(b) Parallel to which axis does the magnetic field oscillate?
(c) When the electric field component is in the positive direction of the z axis at a certain point P, what is the direction of the magnetic field component there?

A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials. A moving charge in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field. The video shows the practical implications of magnetic force around different objects.
