The creation and consumption of cool gadgets has become a way of life for many designers, engineers, and billions of consumers. These gadgets, whether for music, video, Web navigation, games, or communications, keep getting ever more sophisticated, smarter and smaller.

Have you ever experienced virtual devices before? Most of the software development for mobile phone is developed in a dedicated simulator.

By now you have hopefully learned that the voltage induced in a coil is proportionate to the change of the flux threading through that coil. We will now see that this is the cornerstone operating principle for another electromagnetic device called the transformer.

Returning to Faraday’s experiment we concluded the current could be induced to flow in a coil surrounding a magnetic material where the magnetic field in that material was changing.

If you take a wire that is conducting current and you bend it into a loop as we have done in this example, we can see that the magnetic field generated by that wire will be concentrated in the center of the loop as shown.

Ah yes, today we will learn about magnetic fields. Let’s explore how to grow your own magnetic field. And discuss why they are so attractive.

Protecting a company’s intellectual property or IP is one of the highest priorities in a competitive market place. Let’s examine some of the questions listed here.

In a previous article the resistors basic principles have been described and their classification, according to the use and structure, has been shown.

Nowadays most of us have a fast internet connection, either at home or in the office. Lot of data is exchanged over the web with just a mouse click: mails, files, faxes, web pages, videos, chats, phone calls, and so on.

The Fourier transform as a tool for solving physical problems. Fourier series, the Fourier transform of continuous and discrete signals and its properties.
