The magnetic field will become 1.5 T at double of the distance .

Explanation:

Any current caring wire is surrounded by the magnetic field which is  

B = µ0I/2πr    

It can be seen from above equation that magnetic field is inversely proportional to the distance and directly proportional to current. When distance from the wire becomes double, the magnetic field will become half, which is 1.5 T .
