Question 132: 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, $$\phi  = B.A$$
$${{{\mu _0}\left( 2 ight){{\left( {20 	imes {{10}^{ - 2}}} ight)}^2}} \over {2\left[ {{{\left( {0.2} ight)}^2} + {{\left( {0.15} ight)}^2}} ight]}} 	imes \pi {\left( {0.3 	imes {{10}^{ - 2}}} ight)^2}$$

Electromagnetic Induction

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
