Question 351: Electromagnetic Induction

Question

A conductor of length $$5 \mathrm{~cm}$$ is moved parallel to itself with a speed of $$2 \mathrm{~m} / \mathrm{s}$$, perpendicular to a uniform magnetic field of $$10^{-3} \mathrm{~Wb} / \mathrm{m}^3$$. The induced e.m.f. generated is

Accepted Answer

$$\begin{aligned}
& 	ext { } e=-B v l \
& 	ext { Given, } l=5 \mathrm{~cm}=5 	imes 10^{-2} \mathrm{~m}, v=2 \mathrm{~m} / \mathrm{s} 	ext {, } \
& B=10^{-3} \mathrm{~Wb} / \mathrm{m}^2 \
& e=10^{-3} 	imes 2 	imes 5 	imes 10^{-2} \
& e=10 	imes 10^{-5} \mathrm{~V} \
& e=1 	imes 10^{-4} \mathrm{~V} \
\end{aligned}$$

Answer

$$2 	imes 10^{-3} \mathrm{~V}$$

Answer

$$1 	imes 10^{-3} \mathrm{~V}$$

Answer

$$1 	imes 10^{-4} \mathrm{~V}$$

Answer

$$2 	imes 10^{-4} \mathrm{~V}$$
