Question

A freely suspended magnet always rests pointing in the North-South direction. This
property is the:

(a) directive property (b) attractive property

(c) repulsive property (d) polar property

Answer 1

Answer:

A freely suspended magnet always rests in the north-south direction because the magnetic south pole of the earth lies in the geographic north direction and the magnetic north pole of the earth lies in the geographical south direction. As unlike poles attract and like poles repel, a magnet aligns itself in N-S direction.

Answer 2

Earth, like a bar magnet, has its own magnetic field. The earth's magnetic field is created by the rotation of the planet. When the earth spins, the various charged ions in the molten state in the earth's core rotate, causing a current to flow through it.

Explanation:

• The geographic and magnetic axes do not align and form a 17.5-degree angle with each other. The magnetic equator divides the Earth into two hemispheres.
• The hemisphere with the south polarity of earth's magnetism is known as the northern hemisphere, while the hemisphere with the north polarity is known as the southern hemisphere.
• The magnetic field of the Earth does not have a constant value and varies from place to location on the planet, as well as over time.
• The magnetic field of the earth runs from S (geographical south) to N (geographical north) (geographical north). As a result, a free-floating magnet sits in the geographic north-south direction.
• Therefore, correct option is "A"
