Defining the EMF of a Battery in Simple Words

EMF could mean one of two things depending on the context in which it is used. When discussing all-things radiation, EMF stands for electromagnetic field. But, when you come across the term in the context of batteries and cells, it stands for electromotive force.
It’s impossible to imagine a life without batteries. After all, these simple devices are what power up your cellphone, laptop, tablet, pocket calculator, flashlight, virtually every mobile device in existence.
On its own, a battery looks like the dullest thing you’ll ever come across. But the moment you hook it up to something like your smartphone, that little unit turns into your portable power plant and brings your device to life. Without further ado, let’s dive into defining the EMF of a battery in simple words.

Radiation From Flying on Airplanes – Exposure Risks and Protection Tips

When it comes to flying, you hardly ever consider the radiation risk you face from the moment you walk through airport security. With all the electromagnetic fields (EMFs) bombarding you from every direction, you would think that being thousands of feet above the ground would keep you safe from them – at the very least, for the duration of your flight.
Well, you thought wrong. Not only are you exposed to EMFs from all the electronic devices onboard the aircraft, but you also face higher levels of cosmic radiation from outer space than if you were on the ground. This guide takes an in-depth look at everything you need to know about radiation from flying on planes.
