Magnetism I | Magnetic Field Due To Infinite Solid Cylindrical Wire All the best! 1. A long straight wire of radius 'a' carries a steady current 'I'. The current is uniformly distributed across its area of cross-section. The ratio of magnitude of magnetic field B1 at distance a/2 and B2 at distance 2a from the axis of wire is- 1/2 1 2 4 None 2. Which of the following graphs correctly represents the variation of the magnitude of the magnetic field outside a straight infinite current carrying wire of radius 'a' as a function of distance 'r' from the center of the wire? Option (A) Option (B) Option (C) Option (D) None 1 out of 2 Time's up
