Answer #1

a.

Boot Savart law and Ampere's Law is the standard method to find out magnetic field due to current carrying wire.

B.

The advantage of magnetic leviation in all applications is the lack of contact and thus no wear and friction. This increases efficiency, reduces maintenance costs, and increases the useful life of the systemthe concept of magnetic levitation is possible for emgineering applications.
