Home circuit breakers typically have current capacities of around 9.0 A. How large a magnetic field would such a current produce 4 0 cm from a long wire? Express your answer using two significant figures. How does this field compare with the strength of the earth's magnetic field? This field is the same order of magnitude as the earth's field. This field is far larger than the earth's field. This field is far less than the earth's field.
