Is a combination of magnetic and electric fields.
It does not only influence nearby objects, but also penetrates them, as well, as us. We do not feel it, if it is not strong enough. However it can be felt by compass.
Our planet also has its own electromagnetiv field, which protets all living beings from deadly impact of sunbeams and cosmic radiation.
Faraday. Maxwell. Compass. Radio. Microwave oven. Cellular phone. Computers. High-frequency transmitters.
