Concept explainers

The power density of an electromagnetic (EM) wave is proportional to the square of the frequency of electric field (or magnetic field). The moving charge produces both electric field and magnetic field. Electric and magnetic fields are inseparable and ex…

Wave Reflection and Transmission

Reflection is defined as a sudden change in the path of the wave that strikes the boundary between two types of media. The least part of the disturbances coming from the wavelength remains the same within the same area. The reflection of the wave takes p…

Skin Depth

The wire-type conductors are used in the transmission of electrical energy or signals using an alternating current. The electrons are driven apart due to the electric field created nearby the copper conductor surface. The magnetic field changes with the …

Plane wave propagation

Any of the ways how waves travel is known as wave propagation. One can find the difference between longitudinal wave and transverse wave with respect to the direction of oscillation, which is related to the propagation direction. Propagation may occur i…

Textbook Question

Chapter 7, Problem 7.11P

A solenoid of radius a and of length. L is oriented with its axis along the 2 axis over the range -d/2 The coil is tightly wound with wire having density n turns per meter of length, where each turn carries current I. (a) Find H at the origin. Begin with the current loop field (solution to Problem 7.3) modified by replacing the current in that result with I_s = nI dz. I_s is the current in a circular band of length dz on the coil; the solenoid is made up of these bands of current over the entire length, (b) Show that the midpoint field of part a reduces to nI a_z as the solenoid length approaches infinity.
