Chapter 29, Problem 36(choose chapter or problem)
Why is the following situation impossible? Imagine a copper wire with radius 1.00 mm encircling the Earth at its magnetic equator, where the field direction is horizontal. A power supply delivers 100 MW to the wire to maintain a current in it, in a direction such that the magnetic force from the Earths magnetic field is upward. Due to this force, the wire is levitated immediately above the ground.

ANSWER:Step 1 of 7
If a current carrying conductor is placed in a uniform magnetic field, a force acts on the conductor and the direction of force is perpendicular to both length of the element and direction of magnetic field.
