does magnetic field occupy space
well .. actually i have 2 questions.
1:
for example, we cant see 'AIR' but we can feel it , and we can also understand it in terms of mixture of molecules of gases, which are made from atoms of different kinds of basic chemical elements. all i want to say .. we can understand the nature of MATTERS like AIR and electric CURRENT.
what is an magnetic field ? i am sure, they are not made from electrons or somthing like them ! if we bring two magnets of same polarity very close to eachother, we feel some kind of repulsive force. what is this, which i can feel but cant understand, like the example of AIR given above ?
2:
we know that light has both natures, elect. magnetic and photon.
i can understand the travelling of light in vaccume in sence of photones ..energy packets, like a stream, comming from a light source and thus it dose not need any medium and can travell through vaccume where nothing can help it or resist it.
sound waves can only travell trough a medium ( water, air etc etc ).
what about electromagnetic waves ? these are certanly not photons (are they ?).
every thing, like sound wave, current.. need some medium for travelling. how can EM waves travell throug vaccume ?
my these questions may seem some complex or even dumb, but if sombody can clear me .. i'll be very happy and thankfull.
regards
