Question 669Navigation General

The correct answer is D) soft iron. Induced magnetism is found in soft iron, which is a material that can easily become magnetized when placed in a magnetic field, but loses its magnetism when the field is removed. This is in contrast to hard iron, which retains its magnetism once magnetized. The other options are incorrect because: A) hard iron does not exhibit induced magnetism, B) horizontal iron does not specifically experience induced magnetism, and C) vertical iron does not specifically experience induced magnetism. Induced magnetism can occur in both horizontal and vertical iron, but the key distinction is that it is a property of soft iron, not hard iron or iron in specific orientations.
