Explanation / Answer

Current due to wire is i   = 8.0 A      Magnetic field due to straight wireis :                         B = o i / 2r For r = 2 cm = 0.02 m          B = ( 2 x 10-7 * 8.0 ) / 0.02              = 8 x 10-5   T For r = 1 cm = 0.01 m          B = ( 2 x 10-7 * 8.0 ) / 0.01             = 16 x 10-5 T Hope this helps u!
