Consider the following statements and select the correct option which correctly identifies true (T) and false (F).
(i)Magnetic field lines do not intersect because they always travel parallel to each other in North to South direction.
(ii) When a current flows through a straight copper conductor, it gets permanently magnetised.
(iii) The strength of magnetic field at the centre of a circular coil is inversely proportional to the radius of coil.

A

`{:("(i)","(ii)","(iii)"),(T,T,F):}`

B

`{:("(i)","(ii)","(iii)"),(T,F,T):}`

C

`{:("(i)","(ii)","(iii)"),(F,F,T):}`

D

`{:("(i)","(ii)","(iii)"),(F,T,F):}`

To solve the question, we need to evaluate the three statements provided and determine whether they are true (T) or false (F). ### Step-by-Step Solution: 1. **Evaluate Statement (i)**: - The statement claims: "Magnetic field lines do not intersect because they always travel parallel to each other in North to South direction." - **Analysis**: Magnetic field lines do not intersect because at any given point in space, the magnetic field has a unique direction. If two lines were to intersect, it would imply that there are two different directions of the magnetic field at that point, which is not possible. However, the reason given in the statement is incorrect. Magnetic field lines do not travel parallel; they form closed loops from North to South. - **Conclusion**: This statement is **False (F)**. ...
