D. to be structural material
Answer:
F = 0
Explanation:
The magnetic force is described by two expressions
for a moving charge
F = q v x B
for a wire with a current
F = I L xB
bold indicates vectors
let's write this equation in module form
F = I L B sin θ
where the angle is between the direction of the current and the direction of the magnetic field
In this case they indicate that the cable goes from the South wall to the North wall, so this is the direction of the current
The magnetic field of the Earth goes from the south to the north and in this part it is horizontal
Therefore the current and the magnetic field are parallel, the angle between them is zero
sin 0 = 0
consequently the magnetic force is zero
F = 0

Explanation:
Iron is an element that has been known in its pure form for at least 5,000 years. The name "iron" comes from the...
The element symbol for iron is Fe, which comes from the Latin word for iron, "ferrum."
Iron is one of the most plentiful elements. It comprises about 5.6 percent of the Earth's crust and almost all of its core
Iron is a transition metal.
Animals and plants require iron. Plants use iron in chlorophyll, the pigment used in photosynthesis. Humans use iron in hemoglobin molecules in blood to allow for the transport of oxygen to tissues throughout the body.
