Question

1. Assertion A magnetic needle which is free to swing horizontally would be in the magnetic meridian and the
north pole of the needle would point towards the magnetic North pole
Reason The lime joining the magnetic poles is tilted with respect to geographic axis of the carth themagnetic
meridian at a point makes angle with the geographic meridian
​

Answer 1

Answer:

1. Assertion A magnetic needle which is free to swing horizontally would be in the magnetic meridian and the

north pole of the needle would point towards the magnetic North pole. (T)

Reason The lime joining the magnetic poles is tilted with respect to geographic axis of the carth themagnetic

meridian at a point makes angle with the geographic meridian (T)

Answer: a) A is true R is true and R us correct explanation for A. I thinked this answer by my mind, might it can be wrong

Answer 2

The Assertion is wrong but the reason is a true statement.

• When a magnet is free to move in the horizontal plane, it tends to align itself in the north-south direction.
• The north of the needle points towards the magnetic south pole.
• The Earth's magnetic south pole is located near the Earth's north pole.
• The imaginary line that joins the two magnetic poles does not coincide with the Earth's geographical axis, it is tilted.
• The angle between them is called the angle of declination.
