Question

two coins having area in the ratio 1:2 are kept in the same magnetic field

Answer 1

Where the two coils are kept perpendicular to each other then resultant field in one coil is directed along the axis of coil and the other downwards, hence resultant field isAth

$B′= \sqrt{ B2+B2}=2B</p><p></p><p>$

Ratio of magnetic field due to one coil and resultant is

B/B root 2 = 1/ root 2

1:2

Answer 2

Answer:

=> Where the two coils are kept perpendicular to each other then resultant field in one coil is directed along the axis of coil and the other downwards, hence resultant field isAth

B′= \sqrt{ B2+B2}=2B

Ratio of magnetic field due to one coil and resultant is

B/B root 2 = 1/ root 2

= 1:2 ans.
