Electromagnetic Dipole

**Electromagnetic waves** are the combination of **electric** and **magnetic** field waves produced by moving charges. The **electromagnetic wave** is a form of energy emitted by **movement of charged particles**. As it travels through space it behaves like a **wave**. It has an **oscillating electric field component** and an **oscillating magnetic field**. These waves oscillate **perpendicularly** to and in phase with one another.



The **electric field** that oscillates as a function of time will produce a **magnetic field** and a magnetic field that changes as a function of time will produce an **electric field**. Both fields in an electromagnetic wave will **fluctuate in time**, one causing the other to change.



We can find electromagnetic waves in nature or we can create them and use them in modern technology. **AM and FM radio, cellular phones, garage door openers, wireless networks, radar, microwave ovens** and more are examples of their use in our daily life. These devices use electromagnetic waves to transmit data and signals.
