Of most discoveries on earth, the most significant have been possible due to the magical phenomenon we know as magnetism. The Earth itself is one enormous magnet and ancient mariners used this very property to chart their voyages across the high seas in search of new lands and continents. From this simplest application as a direction finder when suspended by a string, magnets and magnetism is put to countless applications in electrical engineering right from household appliances to space shuttle technology.

Electromagnetic energy travels in waves and spans a broad spectrum from very long radio waves to very short gamma rays. The human eye can only detect only a small portion of this spectrum called visible light. A radio detects a different portion of the spectrum, and an x-ray machine uses yet another portion. NASA’s scientific instruments use the full range of the electromagnetic spectrum to study the Earth, the solar system, and the universe beyond.

When you tune your radio, watch TV, send a text message, or pop popcorn in a microwave oven, you are using electromagnetic energy. You depend on this energy every hour of every day. Without it, the world you know could not exist. 

Our Sun is a source of energy across the full spectrum, and its electromagnetic radiation bombards our atmosphere constantly. However, the Earth’s atmosphere protects us from exposure to a range of higher energy waves that can be harmful to life. Gamma rays, x-rays, and some ultraviolet waves are “ionizing,” meaning these waves have such a high energy that they can knock electrons out of atoms. Exposure to these high-energy waves can alter atoms and molecules and cause damage to cells in organic matter. These changes to cells can sometimes be helpful, as when radiation is used to kill cancer cells, and other times not, as when we get sunburned.

Electromagnetic radiation is reflected or absorbed mainly by several gases in the Earth’s atmosphere, among the most important being water vapor, carbon dioxide, and ozone. Some radiation, such as visible light, largely passes (is transmitted) through the atmosphere. These regions of the spectrum with wavelengths that can pass through the atmosphere are referred to as “atmospheric windows.” Some microwaves can even pass through clouds, which make them the best wavelength for transmitting satellite communication signals.

While our atmosphere is essential to protecting life on Earth and keeping the planet habitable, it is not very helpful when it comes to studying sources of high-energy radiation in space. Instruments have to be positioned above Earth’s energy-absorbing atmosphere to “see” higher energy and even some lower energy light sources such as quasars.

All these waves do different things (for example, light waves make things visible to the human eye, while heat waves make molecules move and warm up, and x rays can pass through a person and land on film, allowing us to take a picture inside someone’s body) but they have some things in common.

They all travel in waves, like the waves at a beach or like sound waves, and also are made of tiny particles. Scientists are unsure of exactly how the waves and the particles relate to each other. The fact that electromagnetic radiation travels in waves lets us measure the different kind by wavelength or how long the waves are. That is one way we can tell the kinds of radiation apart from each other.

Although all kinds of electromagnetic radiation are released from the Sun, our atmosphere stops some kinds from getting to us. For example, the ozone layer stops a lot of harmful ultraviolet radiation from getting to us, and that’s why people are so concerned about the hole in it.

We humans have learned uses for a lot of different kinds of electromagnetic radiation and have learned how to make it using other kinds of energy when we need to. DS1 would not be able to communicate with Earth, for example, if it could not produce radio waves.

 It is difficult to envisage today, a world without magnets. A phenomenon which manifests in the enormity of the earth itself needs to be harnessed, controlled and then applied for the benefit of mankind. This needs vision, commitment and the technical knowledge of experts and the will to extract more from the ordinary – a mission statement that forms the core of our thinking at Electro Magnetic Industries.

Founded in 1988 and alternating between Stuttgart and Cologne each year, the EMV has become Europe’s leading platform for electromagnetic compatibility. In addition to the hands-on workshops held in Stuttgart, a scientific conference in the German language takes place in Cologne in even-numbered years.

The wide range of further training options makes day-to-day work in the EMC sector easier for the participants. The event covers all aspects of electromagnetic compatibility and provides experts with a dedicated platform to actively work on creating an interference-free future.

By combining workshops and an exhibition dedicated to electromagnetic compatibility, the EMV covers a wide array of topics and provides first-class additional benefits for participants and speakers as well as an ideal training opportunity with practical relevance for EMC topics.

The comprehensive range of further training options available at the EMV is presented in two formats. The event in Cologne focuses on scientific conference papers by EMC experts while participants in Stuttgart can look forward to hands-on workshops dealing with various topics in electromagnetic compatibility.

In the 40 different half-day workshops at the EMV 2021 in Stuttgart, experts from industry and science will pass on their expertise and insights on EMC applications they have tested themselves.

In addition to focusing on current legislation, speakers will also explore technical domains such as automotive technology, functional safety, and new test methods. At the same time, the workshop program also has traditional topics at its core, as well as basic information for newcomers and those coming from other career backgrounds who are looking to immerse themselves in the specialized world of EMC.

If EMC testing, devices, guidelines, and certifications are your thing, join us at the EMV – the conference and workshops dedicated to electromagnetic compatibility (EMC) – in Stuttgart from 23 – 25 March 2021.

Taking “Creating a compatible future” as its theme, the event provides a comprehensive overview of the latest products and developments in the sector. Come and meet international exhibitors and brush up your knowledge in hands-on workshops.
