An engineer is selecting materials for two devices: a permanent magnet and the core of an electromagnet.
Two metals are considered:
Which option correctly pairs the metals and their suitable applications?
Permanent magnet = Metal X (iron); Core of electromagnet = Metal Y (steel)
Permanent magnet = Metal Y (steel); Core of electromagnet = Metal X (iron)
Permanent magnet = Metal X (steel); Core of electromagnet = Metal Y (iron)
Permanent magnet = Metal Y (iron); Core of electromagnet = Metal X (steel)
