hey, mate here is your
magnetic field due to a circular loop at its centre is given by. ui/2πr. I is current. and r is radius

B1=u(1)/2π(10cm)
B2= u(2)/2π(40cm)

on taking ratio

B1/B2=40/10

B1/B2=4


susmi3: u indicates
susmi3: but options are a.1:1 b.3:1 c.2:1 d.5:1
susmi3: please tell me correct answer
susmi3: tq
