Question

(vi) Which is a natural magnet?
(a) Magnetite
(b) Haemetite
(c) Bakelite
(d) Copper

Answer 1

(a) Magnetite is a natural magnet.

• Magnetite can be described as a naturally occurring ore of iron which is attracted to a magnet.
• Magnetite has the properties to become a permanent magnet.
• In fact, studies have shown magnetite to be the most magnetic out of all compounds which are present on the Earth naturally.
• Other options, such as option (c) Bakelite is not correct because Bakelite is a synthetic plastic which will not have magnetic properties.

Hence, the correct option is (a) magnetite.
