14-26 A certain plane wave in sea water has an rms value for the electric field intensity vector of Ex = 3 V/m, and the dielectric constant is 80. Assume that the magnetic in- tensity vector is in the positive y-direction. Determine (a) the magnitude of the magnetic field intensity, (b) the power density of the plane wave, and (c) the total power transmitted through a square surface in the x-y plane with sides of 15 m each. Assume that the power density is constant over the surface area.

Every material has a unique composition that defines its magnetic behavior. Some materials get attracted towards a magnet and are called magnetic materials. Based on the magnetic properties held by each material, they are classified into different types.
