Example Sentences

Most notably, he had hammered out a model, about 8 inches long and made of soft iron, of the original tool.

From Washington Times

One of the principal results was the discovery that the effect of longitudinal pull is to increase the inductive magnetisation of soft iron, and of transverse thrust to diminish it, so long as the magnetising field does not exceed a certain value.

From Project Gutenberg

This principle of operation may be illustrated by a simple experiment: Place end to end, and preferably in actual contact, a permanently magnetized steel bar and a strip or bar of soft iron.

From Project Gutenberg

At one end of the lever A is a soft-iron armature block, a, over the core M' of the helix M, and there is a limiting screw, c, passing through this armature block a, and at the other end of the lever A is a soft iron armature block, b, with the end tapering or wedge shaped, and the same comes close to and in line with the lateral projection e on the core N2.

From Project Gutenberg

The action is based on the magnetic inertia of iron; for this reason a disc of hard steel is much more affected than a disc of soft iron, the latter being capable of very rapid variations of magnetism.
