Marks: +1, -0

Two concentric circular loops, one of radius R and the other of radius 2R, lie in the xy-plane with the origin as their common center, as shown in the figure. The smaller loop carries current I1 in the anti-clockwise direction and the larger loop carries current I2 in the clockwise direction, with I2>2I1,B(x,y) denotes the magnetic field at a point (x,y) in the xy-plane. Which of the following statement(s) is(are) correct?

[JEE Adv 2021 P2]

B(x,y) is perpendicular to the xy-plane at any point in the plane
|
→
B
(x,y)| depends on x and y only through the radial distance r−√x2+y2
|B(x,y)| is non-zero at all point for r<R
→
B
(x,y) points normally outward from the xy-plane for all the points between the two loops
