depends. magic as in being able to see it? not really, some people can see or feel energy that is magic, but it's like spirits, not many can see/feel them.
it comes down to belief, and i know how difficult it is to believe in something that doesn't have a ton of evidence besides what someone experiences. magic is real because i've seen it work, it's not like in the movies, it's more of a way to help the odds in your favour in most situations. one of the more recent spells i cast was a jar spell for my mom who just wanted to have someone to go to the movies with and stuff as a friend. a week or two later a friend of our landlords [who came by on occasion, but we weren't close] invited her out to a jazz club with some people. it's been a year now, and the group meets twice a month for stuff.
Well if your into science you can see magick as energy. Magick is energy. Both can't be created or destroyed. You cannot see energy. Does that mean it doesn't exist? There both the same. It's kind of like kenetic, potential, etc energy. =)
But could this just be coincidence? Your mind making connections? It's kind of like religion, huh? You pray to God to get someone to go out with you and then it happens. Connections in the mind. Sorry if I'm offending your beliefs in magic BTW.
I was reading a post on alchemy which is basically chemistry mixed with magical elements to 'transmute' something or create a golem. Has anyone done this? That's hard evidence.
