Nothing will happen to the magnetic field.
BUT If you're talking about the magnetic force , then when changing the current direction , the direction of the magnetic force will be reversed.
(You'ld like to know :
-Changing direction of current ONLY , reverses the direction of magnetic force.
-Changing direction of Magnetic field only (poles of magnet) , reverses the direction of magnetic force.
-Changing the direction of both , magnetic field and current , doesn't effect direction of magnetic force.)
N.B : Magnetic Force is experienced only when direction of current is PARALLEL to direction of magnetic field .
--> Flemming Left Hand Rule is used to know direction of magnetic force.
Hope This Helps.
