Angel magick is asking your angels and or spirit guides to help aid you in receiving the item you want.They also help you to see what is what is best for your future. I do not know exactly what demon magick is but if it is done by harming anyone it is not good magick
Sharona22 is correct. Angel magick is to ask your own Guardians or Spirit Guides to aide you. Demon Magick can involve bad and good demons. Yes there are good demons, but have been condemmed to seem bad. Take Lucifer for an example. He is still noted as an Archangel.
If you have ever read the Book Of Angels, he is still considered the 7th Archangel. Though Satan only means "Traitor" like in Wicca, warlock means "Traitor".
Archangels are not always good. Archangel speaks of the power of the angel in question. The archangels are the most powerful of the angels. By that definition, it's easier to see how Lucifer still numbers among them. However keep in mind that the list of seven archangels differs depending on who you ask. There are several lists and they don't all agree on who the seven of them are.
There are many forms of Angelic magic, as far as I am currently aware Enochian magic is the most potent and ancient of the type. The majority of the work is on expansion and betterment of the soul, and how to cause effects in this world through their system.
Demonic magic would usually be summoning demons for a specific purpose, but as with angelic magic it doesn't Have to be so cut and dry. I believe that good and evil are human concepts, and it is both unfair and inapproperiate to fully apply such concepts to beings that are more spiritually evolved then most of humanity.
Angels and Demons both have the capacity to cause us harm, some have such high energy that their very presence disrupts ours and causes discomfort to pain.
I also recommend leaving both angel and demon alone until you have a fair bit of knowledge of magic, it can be quite draining and demanding work to better the soul and the knowledge and benifits either side provides are not easily taken in by a person whom has little grasp of magic.
Its quite dangerous to jump into Angel magic or Demon magic without having gone through steps first, for example with Demon work you do need to be able to deal with them when they come through.
People believe that Angel magic is good, and that Demon magic is bad, but its not really that simple to say that because I get more safer results through Demon magic.
Common misconceptions about angels being all positive won't help any of these new-agers jumping in to it. I refer to it as entitity magick, so there's no preconception that the entity involved is good or evil.
