A 10-turn coil of wire having a diameter of 1.0 cm and a resistance of 0.30 Ω is in a 1.0 mT magnetic field, with the coil orien
AlekseyPX

Answer:

The voltage across the capacitor = 0.8723 V

Explanation:

From the question, it is said that the coil is quickly pulled out of the magnetic field. Therefore , the final magnetic flux linked to the coil is zero.

The change in magnetic flux linked to this coil is:

\delta \phi  = \phi _f - \phi _i

    = 0 - BA cos 0°

\delta \phi  =-BA \\ \\ \delta \phi  =-B( \pi r^2) \\ \\ \delta \phi  =(1.0  \ mT)[ \pi ( \frac{d}{2} )^2]

\delta \phi  =(1.0  \ mT)[ \pi ( \frac{0.01}{2} )^2]

\delta \phi  = -7.85*10^8 \ Wb

Using Faraday's Law; the induced emf on N turns of coil is;

\epsilon = N |\frac{ \delta \phi}{\delta t} |

Also; the induced current I = \frac{ \epsilon}{R}

\frac{ \delta q}{ \delta t}  = \frac{1}{R} (N|\frac{\delta \phi}{\delta t } |)

\delta q = \frac{1}{R} N|\delta \phi |

\delta q = \frac{1}{0.30} (10)| -7.85*10^8 \ Wb |

\delta q = 2.617*10^{-6} \ C

The voltage across the capacitor can now be determined as:

\delta \ V =\frac{ \delta q}{C}

= \frac{ 2.617*10^{-6} \ C}{3.0 \ *10^{-6}  F}

= 0.8723 V
