ignore 7.6
7.7 W hich of these statements is not characteristic of a static magnetic field:? (a) It is solenoidal. (b) It is conservative. (c) It has no sinks or sources (d) Magnetic flux lines are always closed. (e) The total number of flux lines entering a given region is equal to the total numbet flux lines leaving the re 10 A 10 A O 30 A 30 A 10 A L/ 10 A 30 A 30 A 7.8 Two identical coaxial circular coils carry the same current I but in opposite directions. The magnitude of the magnetic field B at a point on the axis midway between the coils is (a) Zero (b) The same as that produced by one coil (c) Twice that produced by one coil (d) Half that produced by one coil.Explanation / Answer
