How did my professor 1.269x10^-4 for part B whenever I do the calculations I get 1.269x10-7

Problem 7: You are given a coil with a current of I:=10.00. A moving through its wires. if the coil has N:=1000, is a length of Levi:=10.0. cm, (a) what magnetic field will be measure inside the coil. (b) If the area of the coil is Acy :=1.01 . mm what will be the magnetic flux through the coil due to its own magnetic field? (c) what is the self inductance of this coil? (a) Broil N . Icoil . Ho= 0.126 T L coil (6) :=N . Bcoil . Acoil = (1.269 - 10 ) T.m (c) Linductor := N' . Acoil Ho (1.269 - 10 5) H Leoil
