Answer 1

Hey Friend, YOUR answer is :-

d) The intensity of magnetic field in A is less than in B.

This is because, In A resistors are connected in series whereas, in B resistors are connected in parallel. So, the current flowing through the coil in B will be more then in A.

Answer 2

ANSWER IS (D)

FROM LOGIC POINT OF VIEW

IN PARALLEL COMBINATIONS THE RESISTANCE IS LESS THEREFORE THE CURRENT WILL BE MORE AND THE MAGNETIC FIELD LINES ARE DIRECTLY PROPOTIONAL TO MAGNETIC FIELD LINES HENCE ANSWER IS ( D )

FROM GUESSING POINT OF VIEW

OPTIONS A AND B ARE ONE AND THE SAME THEREFORE THEY BOTH ARE NOT POSSIBLE BECAUSE THIS QUESTION IS ASKING FOR ONE ANSWER

SO UR ANSWER SHOULD BE C OR D

IT SOMETIMES HELP IN GUESSING IN COMPETITIVE EXAMS WHEN U HAVE LESS TIME

HOPE IT HELPS

THANK YOU
