Explanation:

1:If the magnitude of current is increased ,then the deflection of the compass will increase as the electric field created by the wire in turn creates a magnetic field which deflects the compass needle. Magnetic field strength is directly proportional to the amount of current.

2:)if it is displaced from the wire then the deflection will decrease as the magnetic field becomes weaker with increase in distance. Deflection of compass needle decreases : Magnetic field strength is inversely proportional to the distance from wire.
