: Suppose A Straight 1 50 Mm Diameter Copper Wire Could Just Float Horizontally In Air Because Of The Force Due To The 2 (9.71 KiB) Viewed 41 times

Suppose a straight 1.50 mm -diameter copper wire could just "float" horizontally in air because of the force due to the Earth's magnetic field B, which is horizontal, perpendicular to the wire, and of magnitude 5.3x10-5 T.

What current would the wire carry? SHOOO our answer using two significant figures.
