Final answer:
The magnetic field 55 cm from the wire carrying 1100 A is 4 x 10^-5 T.
Step-by-step explanation:
To find the magnetic field 55 cm from a straight wire carrying 1100 A, we can use Ampere's law:
B = μ0 * I / (2π * r)
where B is the magnitude of the magnetic field, μ0 is the permeability of free space (4π x 10^-7 T*m/A), I is the current in the wire, and r is the distance from the wire.
Plugging in the values, we have:
B = (4π x 10^-7 T*m/A) * (1100 A) / (2π * 0.55 m) = 4 x 10^-5 T
So, the magnetic field 55 cm from the wire is 4 x 10^-5 Tesla.
