Which pair contains two metals that a magnet attracts?

  1. Copper and zinc
  2. Iron and nickel
  3. Gold and silver
  4. Lead and tin
Show answer and solution

Correct answer: B. Iron and nickel

1. Ferromagnetic metals include iron, nickel and cobalt. 2. So iron and nickel are both attracted. 3. The other pairs hold only non-magnetic metals. _Source: Wikipedia, Magnet, Lead section_
