The class is about Electricity and Magnetism. The website wants exactly the perfect answer and in the same metric system units that are stated on the calculators that are on the picture for the question, if not, it'll mark it wrong.

Magnetic Levitation A straight 2.27-mm-diameter copper wire can just 'float' horizontally in air because of the force of the Earth's magnetic field B, which is horizontal, perpendicular to the wire, and of magnitude 5 x 10"- T. What current / does the wire carry? (The density of copper is 8.96 g/cm 5 I = A abc sin(x) Ox10 Submit Reset Reset All .The wire feels a downward gravitational force of magnitude mg, where m is mass and g = 9.80 m/s is the gravitational field strength near the Earth's surface
