Answer:
A magnet is made of iron or an iron alloy with a strong attraction to another metal object that generates or produces its own magnetic force, called magnetic field. Despite being invisible, a magnet’s magnetic field is responsible for producing the force that attracts other objects. Only metals such as iron, nickel, cobalt, and rare Earth metals are attracted to magnets but not all metals are, and these materials are called magnetic. Objects that are not attracted to magnets are called non-magnetic. Examples are silver, gold, wood, and plastic.
So YES, cobalt is attracted to magnet.
