Protection from 'nazr'

What exactly is ‘nazr’ according to Sharia? Intentional or Unintentional.

I know it is not like black magic or casting jinns/spirits etc. So how one’s nazr can harm or change other’s fate or destiny. For example we hear a lot that someone was doing good in business and then all of a sudden it trumbles which is followed by series of disasters in his/her life. Could it be a chain of coincidents of mishaps?

How do we protect from ‘nazr’? Masnoon practice only.
