Step 1 · Read the article

Open the article and read it at the level above. Then answer the questions below in your own words.

Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the primary mechanism?Exploits differential magnetic susceptibility of materials
2. What is the industrial role?Essential for ore beneficiation, metal recycling, and contaminant removal
3. Why do magnets pull iron but not gold?Iron, nickel, and cobalt are ferromagnetic, so they are strongly attracted to magnets. Gold, silver, and aluminum are non‑magnetic, so they stay away.
4. How do magnetic separators work in factories?In factories, a rotating drum or belt carries a mixture. Magnetic parts stick to the drum and fall off when the magnet is weaker, leaving the rest behind.

Magnetic Susceptibility: A measure of how much a material becomes magnetized in an external magnetic field.
Ferromagnetic Materials: Substances that exhibit strong attraction to magnetic fields and can be permanently magnetized.
Ore Beneficiation: The process of improving the quality of an ore by removing waste material, often using physical separation methods.
