Explanation:
This problem can be solved by using the equation
B = (μ0*I)/(2π*r) ( 1 )
where μ0 is the magnetic permeability, I is the current in the wire and r is the distance to the wire, where the magnetic field B is calculated. The equation (1) says that a current in a wire produce a magnetic field in a distance r from the wire.
Part A
Taking into account that μ0 =
By replacing in the equation ( 1 ) we have:
Part B
In tis case is only necessary to calculate B/Be (Be is the magnetic field of the earth), but taking into account that tha magnetic field of the earth must be in teslas.
1 gauss = 10^(-4) T
0.50 gauss = 0.50*(10^(-4)) T = 5*10^(-5) T
Hence, the proportion between B and Be:
Thus, it is only 9% of the magnetic field of the earth.
