Ferromagnetic substances
Understand the Problem
The question is asking about ferromagnetic substances, which refers to materials that can be magnetized and have a high magnetic permeability. This often includes elements like iron, cobalt, and nickel, and the question could be looking for definitions, examples, or applications of these substances.
Answer
Iron, cobalt, nickel, gadolinium, neodymium, and some alloys.
Ferromagnetic substances include iron, cobalt, nickel, gadolinium, neodymium, and some alloys or compounds containing these elements.
Answer for screen readers
Ferromagnetic substances include iron, cobalt, nickel, gadolinium, neodymium, and some alloys or compounds containing these elements.
More Information
Ferromagnetic materials exhibit strong magnetization properties even without an external magnetic field. Gadolinium and neodymium are rare-earth elements that also show ferromagnetism.
Tips
A common mistake is to assume all metals are ferromagnetic, but only a few specific elements and compounds exhibit this property.
