Topic: Electromagnetics
What is the value of magnetic flux in Weber, if it is 2000 in Maxwell?
- A. $2\times 10^{-5}$
- B. $2\times 10^{-3}$
- C. $2\times 10^5$
- D. $2\times 10^3$
Answer: A. $2\times 10^{-5}$
Explanation: The conversion factor between Maxwells (CGS unit) and Webers (SI unit) for magnetic flux is $1\text{ Weber} = 10^8\text{ Maxwells}$. Therefore, $2000\text{ Maxwells} = 2000 imes 10^{-8}\text{ Webers} = 2 \times 10^{-5}\text{ Webers}$.
