Consider a wire carrying a current due east in a location where the Earth’s field is due north. A) What is the direction of the force on the wire if both are parallel to the ground?  B) Calculate the force per unit length on the wire, in newtons per meter, if the wire carries 19.5 A and the field strength is 2.85 × 10-5 T.  C) What would the diameter be, in meters, of copper wire (with density ρ = 8.80 × 103 kg/m3) that would have its weight supported by this force in meters?  D)  Calculate the resistance per unit length, in ohms per meter, that this copper wire will have.
