The weakest magnetic field has a magnitude and a direction of 0.04323 T. Magnetic force = magnetic field * length * current magnetic force = magnetic field * 0.0505 * 8.08 This force must be equivalent to gravity force in order to maintain wire.

mg = magnetic field * 0.0505 * 8.08 1.8 * 10-3 * 9.8

= magnetic field * 0.0505 * 8.08

magnetic field = 0.04323 T The magnetic field will be generated in the opposite direction to that of the current-carrying wire.

By magnitude, what do you mean?

"Distance or amount" is the simplest definition of magnitude. It shows the size or direction that an item travels in either an absolute or relative sense. Magnitude in physics often describes a length or a size.
