Question 117: Electromagnetic Induction

Question

A circular loop of radius $0.3$ $cm$ lies center of the small loop is on the axis of the bigger loop. The distance between their centers is $15$ $cm.$ If a current of $2.0$ $A$ flows through the smaller loop, than the flux linked with bigger loop is

Accepted Answer

As we know, Magnetic flux, $\phi  = B.A$
${{{\mu _0}\left( 2 ight){{\left( {20 	imes {{10}^{ - 2}}} ight)}^2}} \over {2\left[ {{{\left( {0.2} ight)}^2} + {{\left( {0.15} ight)}^2}} ight]}} 	imes \pi {\left( {0.3 	imes {{10}^{ - 2}}} ight)^2}$
