Wireless Power Transmission - Essay Example As the stydy highlights low power devices that include mobile phones and digital cameras use batteries which are charged. In cases where one has many low power devices and intends to charge them simultaneously, it becomes a tedious affair. Current manufacturers make electronic gadgets with varying charging systems. To curb the messy picture of using wired systems, wireless power transmission comes handy and an effective way to charge portable and low-power gadgets. From this study it is clear that electromagnetism is considered to be the study of physical interaction occurrences placed between electrically charged elements. The power of electromagnetism manifests as a field, which is one of the major four fundamentals in natureÃ¢â¬â¢s interactions leaving the other three as gravitation, weak interaction, and strong interaction. Ã¢â¬Å"WPT is carried out using either the Ã¢â¬Å"near-fieldÃ¢â¬ electromagnetic (EM) induction (e.g., inductive coupling, capacitive coupling) for short-term distance (say, less than a meter) applications such as passive radio-frequency identification, or the Ã¢â¬Å"far-fieldÃ¢â¬ EM radiation in the form of microwaves or lasers for long-range (up to a few kilometers) applicationsÃ¢â¬ . Lorentz force is an electromagnetic phenomenon which including both electric and magnetic elements of a single phenomenon. The force of electromagnetism plays a significant role in the determination of the functions of the objects we encounter every day . Ordinary things then aquire the form resulting from intermolecular forces that are between the individual matter molecules. Electrons are bound by electromagnetic wave mechanics to form building blocks of molecules called atoms.
