"hi guys I need someone to tell me. The magical power on our body is like charmed witches?"
Hollywood is just that, fiction. Witches don't throw fireballs, make light come out their finger tips, etc.
Witchcraft and magic is instead will, intent, and action to manipulate the world around you, namely through the unseen.
Take shapeshifting. Last night I went into trance and shapeshifted into a snake. Did my body change? No.
I flew from my form into that of a snake, and lived as it for a time. None of this required me to physically change form.
