Application +4 | -1

Two concentric rings are kept in the same plane. Number of turns in each ring is

\mathbf{2 5}

. Their radii are

50 \mathrm{~cm}

and

200 \mathrm{~cm}

and they carry electric currents of

0.1 \mathrm{~A}

and

0.2 \mathrm{~A}

respectively, in mutually opposite directions. The magnitude of the magnetic field produced at their centre is

\_\_\_\_\_\_\_

View answer and explanation

Correct option: D

\frac{5}{4} \mu_0

Option D (

\frac{5}{4} \mu_0

) is correct because it is the correct calculation of the net magnetic field at the center due to both rings.
