Problem

An external magnetizing field of the same magnitude is applied separately to pure iron, aluminum, and bismuth (a strongly diamagnetic substance). Which ranking of the resulting magnetic flux density BB inside each sample is most likely? (a) Biron>Bbismuth>BaluminumB_{\text{iron}} > B_{\text{bismuth}} > B_{\text{aluminum}} (b) Baluminum>Biron>BbismuthB_{\text{aluminum}} > B_{\text{iron}} > B_{\text{bismuth}} (c) Biron>Baluminum>BbismuthB_{\text{iron}} > B_{\text{aluminum}} > B_{\text{bismuth}} (d) Bbismuth>Baluminum>BironB_{\text{bismuth}} > B_{\text{aluminum}} > B_{\text{iron}}
