Question

Which of the following is the correct statement about a magnetic compass?

• A. Compass works only in oceans or seas.
• B. Compass works at all the places within the Earth's magnetic field.
• C. Compass works only on land, where the earth's magnetic field is strong.
• D. Compass works everywhere including the space far from Earth.

Answer 1

The correct option is B Compass works at all the places within the Earth's magnetic field.

A magnetic compass works at all places on the Earth but within its magnetic field influence. In space, very far from the Earth, the compass will not work as it needs an external magnetic field to balance in a particular direction.
