Vedclass · Answer

(a) Point $P$ lies on equatorial line of magnet $(1)$ and axial line of magnet $(2)$ as shown

${B_1} = \frac{{{\mu _0}}}{{4\pi }} \cdot \frac{M}{{{d^3}}} = {10^{ - 7}} 	imes \frac{{1000}}{{{{(0.1)}^3}}} = 0.1\,T$
${B_2} = \frac{{{\mu _0}}}{{4\pi }} \cdot \frac{{2M}}{{{d^3}}} = {10^{ - 7}} 	imes \frac{{2 	imes 1000}}{{{{(0.1)}^3}}} = 0.2\,T$
$	herefore$  ${B_{{m{net}}}} = {B_2} - {B_1} = 0.1\,T$
