Question

Following is equilateral triangle shape loop, whose one arm produces magnetic field B at the centre. The resultant magnetic field due to all the arms will be :- (A) 4B (B) B/2 (C) Zero (D) 3B

Tardigrade Admin · Accepted Answer

All the wires will produce magnetic field of magnitude B, out of the plane of paper. So, B text net =3 B

Q. Following is equilateral triangle shape loop, whose one arm produces magnetic field $B$ at the centre. The resultant magnetic field due to all the arms will be :-

4B

B/2

Zero

3B

All the wires will produce magnetic field of magnitude $B$ , out of the plane of paper.
So, $B_{net} = 3 B$
