for coil A:
VA=25cm=0.25m
nA=24nA=24
IA=10AI=10A
For coil B:
rb=15cm=0.15m
nb=18nb=18
Ib=15AI=15A
Magnetic field at the center of coil x
BA=µ0 /4π*2Ia πna/ra
=10−7×2×10×3.14×24/0.25
=6.028×10^−4
=6.028×10^−4T
Magnetic field at the center of coil B
B= µ0 /4π*2Ib πnb/rb
=10−7×2×3.14×15×18
=11.30×10−4T
Hence the net magnetic field at the center
Bb−Ba=(11.30×10−4−6.028×10−4)T
=5.27×10−4T
