G1 Physics · Accepted Answer

For magnetic susceptibility versus magnetising field, the graph is approximately horizontal → III. Inside a uniformly current-carrying wire: B ∝ r so the graph is a straight line through the origin → I. Outside a long straight current-carrying wire: B ∝ 1/r so the graph is a decreasing hyperbola → IV. Inside a long solenoid, magnetic field is nearly uniform in the central region and decreases near the ends → II. Therefore: A-III, B-I, C-IV, D-II According to the source paper, the keyed answer i…
