Question

In which of the following places on the earth, a bar magnet will become almost vertical to the ground if suspended freely?

• A. At the North pole
• B. At the South pole
• C. At the equatorial region
• D. At the tropical region

Answer 1

Answer: (A), (B)

The correct options are
A At the North pole
B At the South pole

At the North pole and the South pole, a bar magnet will point vertically because the magnetic north pole and the south pole are near the geographical South pole and North pole, respectively. Since the attraction is the strongest at the poles of a magnet, the bar magnet will stand vertically at the poles.
