I have the visa from 4 Feb till 4 march but i wish to go there on 1st Feb. Is it possible to enter Norway before the 4 February?
Not on that visa, no, as it's outside its period of validity.
However, if you really, really want to go before February 4th, your only option at present would be to obtain a new visa that covers the period you actually want to travel.
No you cannot. They won't even let you board on the plane to Norway (or any other destination where you need a valid visa) if it seems you won't be able to legally enter the country at the arrival time. Taking a flight the day before would in that sense be acceptable in case of an overnight journey, but that doesn't seem to be your case.
