RE: Physics - Electromagnetism - Electric field energy and density
What are are practical applications of electromagnetism in our everyday life?
What are are practical applications of electromagnetism in our everyday life?
Everywhere!
All electronic devices are based around Electromagnetism!
You may not need to know a lot about this to use those things in your daily live, but either way electricity would not be possible without DC and AC currents physics! Understanding the way that this energy "flows" through metal/conductive cables and how we can insulate them is very important, cause else we would see ourselfes being hit by electricity every day.
Also, how would you know what Ampere, Volt, Watt and other metrics that we see in our daily lifes mean? You don't just go and grab a new battery for your phone, you always have to check that it has the right voltage and ampere capacity (sometimes more might be better!). Wattage is how much electricity you use and by checking the power consumption of electronic devices you can reduce your bill drastically by not using those devices that much or by buying "new" ones that consume less energy :)
