Question

The directive property of a magnet is used in the.
A. Construction of compass
B. Construction of transformer
C. Construction of generator
D. None of the above

Answer 1

The directive property of a magnet has its roots in the magnetism. The magnet produces a magnetic field around it and a magnet has two poles- the north pole and the south pole. Magnetic poles always exist in pairs. The directive property helps to understand which pole of the magnet is north and south.

Complete step by step solution:
The directive property of a magnet explains its tendency to align itself along an external magnetic field. When a magnet is suspended freely in air with the help of a thread then it tends to align itself in the geographic north-south direction. This property of magnet is known as directive property of target.
The directive property of magnet is used in the construction of a compass. Compass is an instrument which is used for navigation and orientation that show direction relative to geographic cardinal points.

Additional Information: The magnetic compass functions as a pointer to magnetic worth, which helps mariners to determine their direction. The magnets are very useful in our everyday lives.

Hence, the correct option is (A)

Note: The compass is based on the property of a freely pivoted magnet which aligns itself along the north-south direction. The compass has a tiny magnet in the form of a needle which can rotate or move freely on a pivot or pin.
