Homework Statement
a long straight 6mm diameter conducting wire is carrying a current of 4A.
1)What is the magnitude of the magnetic field at a point 1mm inside the surface of the wire.
2)what is the magnitude of the magnetic field at a point 2cm from the centre of the wire
Homework Equations
using amperes law:
for part 1 i got 44*10^-9
and for part 2: 50*10^-9
I wnt to make sure i have done it right though, becuase it is a past exam question that i don't have solutions for. So if anyone is good at these questions, it would be helpful to check my answers in case i have stuffed up.
