Question

Which of the following properties of a magnet is/are used in navigation?

• A. Pair property
• B. Laws of magnetic poles
• C. Directional property
• D. Attractive property

Answer 1

The correct option is C

Directional property

1. During the middle ages, crude navigational compasses were made by attaching pieces of lodestone to wooden splints floating in bowls of water; These splints were always found to come to rest in a North-South direction and were the forerunners of the modern aircraft and ship compasses.
2. A compass has directional properties.
3. Thus, the directional property of a magnet is used in navigation.

Thus, option(C) is the correct answer.
