Question

A cyclist stationary bicycle at one revolution per second .The pedals attached to a turn coil of area 0.1meter square and placed in a magnetic field 0.1 Tesla.what is maximum voltage developed?

Answer 1

Given:

The bi-cycle wheel rotates at 1 revolution per second. The pedals are attached to 0.1 m² area and placed in a magnetic field of 0.1 Tesla.

To find:

Max voltage developed.

Calculation:

According to Faraday's Law of Electromagnetic Induction, the maximum voltage developed will be equal to the rate of change of magnetic flux.

Since the padals complete 1 revolution in 1 second, the time for change of flux through the plates is 1 sec.

$\therefore \: E = \dfrac{ \phi}{t}$

$= > \: E = \dfrac{B \times A}{t}$

$= > \: E = \dfrac{0.1 \times 0.1}{1}$

$= > \: E = \dfrac{ {10}^{ - 2} }{1}$

$= > \: E = {10}^{ - 2} \: volt$

So, final answer is:

$\boxed{ \red{ \bold{ \large{ \: E = {10}^{ - 2} \: volt}}}}$
