Question

Adithya peddles a stationary bicycle, the pedals of which are attached to a $500$ turns coil of area $11{\text{m}}^2$. The coil rotates at half a revolution per second, and it is placed in a uniform magnetic field of $20.5\text{T}$ perpendicular to the axis of rotation of the coil. What is the maximum voltage generated in the coil?

Take $\pi =3.14$

• A. $354035\text{V}$
• B. $304035\text{V}$
• C. $334035\text{V}$
• D. $314035\text{V}$

Answer 1

The correct option is A $354035\text{V}$

Maximum voltage generated,

$E_0=NBA\omega$

$\Rightarrow E_0=500\times 20.5\times 11\times (2\pi \times 0.5)$

$\Rightarrow E_0=354035\text{V}$
