Question 130

An engineer is selecting materials for two devices: a permanent magnet and the core of an electromagnet.

Two metals are considered:

  • Metal X is magnetically hard (difficult to magnetize but retains its magnetism).
  • Metal Y is magnetically soft (easily magnetized and demagnetized).

Which option correctly pairs the metals and their suitable applications?

A

Permanent magnet = Metal X (iron); Core of electromagnet = Metal Y (steel)

B

Permanent magnet = Metal Y (steel); Core of electromagnet = Metal X (iron)

C

Permanent magnet = Metal X (steel); Core of electromagnet = Metal Y (iron)

D

Permanent magnet = Metal Y (iron); Core of electromagnet = Metal X (steel)
