Question 144: Electromagnetic Induction

Question

A metal conductor of length $$1$$ $$m$$ rotates vertically about  one of its ends at angular velocity $$5$$ radians per second. If the horizontal component of earth's magnetic field is $$0.2 	imes {10^{ - 4}}T,$$ then the $$e.m.f.$$ developed between the two ends of the conductor is

Accepted Answer

$$\ell  = 1m,\,\,\omega  = 5\,rad/s,\,\,B = 0.2 	imes {10^{ - 4}}T$$
$$\varepsilon  = {{B\omega {\ell ^2}} \over 2} = {{0.2 	imes {{10}^{ - 4}} 	imes 5 	imes 1} \over 2} = 50\mu V$$

Answer

$$5mV$$

Answer

$$50\mu V$$

Answer

$$5\mu V$$

Answer

$$50mV$$

Electromagnetic Induction

A metal conductor of length $1 m rotates vertically about one of its ends at angular velocity 5 radians per second. If the horizontal component of earth's magnetic field is 0.2 \times {10^{ - 4}}T, then the e.m.f.$ developed between the two ends of the conductor is
