Question

consider the following statements the direction of magnetic field at the point A. is taken to be the direction in which the north pole of a magnetic compass needle points B. magnetic field lines are closed curves C. if magnetic field lines are parallel and equidistant their present zero field strength D. relative strength of magnetic field is shown by the degree of closeness of the field lines the correct statements are a .a n d only b c and d only c a b and c d a b and d​

Answer 1

Answer:

D) A ,B and D is the correct answer

Answer 2

The correct answer for this question is a,b and d

Explanation:

• Earth itself has a magnetic field which is similar to that of a bar magnet. The compass needle aligns with the Earth's magnetic field direction and points north-south. So A is correct option.

• They form continuous curves because field lines begin from north and end in south side. hence they form closed curves. Hence B is also correct.

• magnetic field lines are parallel and equidistant their present zero field strength.Parallel and equidistant magnetic field lines represent uniform and constant field strength. Hence C is wrong.

• Relative strength of magnetic field is shown by the degree of closeness of the field lines.This is mainly because of the magnetic flux present.Hence D is also correct.
