$L i m i t A \to \infty :$

$X_{0} = \frac{1}{β} X_{s} \Rightarrow V_{0} = \frac{R_{1} + R_{2}}{R_{1}} V_{i n}$

$X_{i} = 0$

Drawing 1

$V_{i n} = V_{0} (\frac{R_{1}}{R_{1} + R_{2}})$ .

$V_{0} = \frac{1}{(\frac{R_{1}}{R_{1} + R_{2}})} V_{i n}$

Magnetic Circuits

$\vec{F} = q \vec{v} \times \vec{B}$

$d \vec{F} = I d \vec{l} \times \vec{B}$
