Solution

Q.
The magnetic field B crossing normally a square metallic plate of area ${4m}^{2}$ is changing with time as shown in the figure. The magnitude of induced emf in the plate during $t = 2 s$ to $t = 4 s$ is __________ mV. [2023]

Ans.
(8)

$m = \tan θ = \frac{10}{5} = 2$

$B = m t$

$B = 2 t$

$ε =$ $| \frac{d ϕ}{d t} |$ $= \frac{d (B A)}{d t} = \frac{A d B}{d t}$

$ε = \frac{4 d (2 t)}{d t} = 4 \times 2 = 8 mV$
