Niobium metal becomes a superconductor (with electrical resistance equal to zero) when cooled below 9 K. If superconductivity is destroyed when the surface magnetic field exceeds 0.100 T, determine the maximum current a 2.00-mm diameter niobium wire can carry and remain superconducting. (0 = 4p  10-7 Tm/A)
 a. 2000 A
  c. 125 A
  b. 1000 A
  d. 500 A

Question 2

 a. kgs2
  c. kg/s2
  b. kg/m2
  d. kgm2
