suppose a straight 1.00mm-diameter copper wire could just float horizontally in air because of the force due to the Earths magnetic field B, which is horizontal, perpendicular to the wire, and of magnitude 5.0*10^-5T. What current would the wire carry? Does the answer seem feasible? Explain please because this doesnt make sense!!

The only time elec is induced into the wire is when the magnetic field is changing provided it cuts into the wire / wire's field.
If you had a stable magnetic field then the only two times you would see any current in the wire would be upon entering the field (creating the magnetic field) and exiting the field ( collapsing the magnetic field). If .. and only if the magnetic field's lines of flux cut into the wire / wire's magnetic field.

No current would be carried in the wire as no flux is being cut, you must cut magnetic flux lines to generate a current.

A good example of this is a large passenger aircraft which generates a potential of around 1 - 2 volts as it flies through the air, as it cuts the flux of the Earth's magnetic field.

Magnetic container is the area round a magnet the position magnetic pressure is experienced.those magnetic container varieties concentric circles for a modern wearing conductor.and the closer the concentric circle the more desirable the pressure experienced. in accordance to Faraday's regulation of pressure and distance(the pressure,F between 2 fee merchandise A and B(charm or repulsion) is inversely proportional to the sq. of their distance) as such is analogous for a magnets.ie the closer the magnet the better the magnetic container and the more desirable the pressure experienced and vice versa.
