Answer 1

$\sf{\red{Answer→ }}$

• Emf due to change in magnetic Field

➥$\sf{\red{EMF =}}$ $\frac{dϕ}{dt}$

➥A [/tex] $\frac{dB}{dt}$

➥πa² [/tex] $\frac{d(B o Cos(ω t))}{dt}$

➥πa²B o ω sin(ω t)

$\sf{\red{Cur.rent\:is\: in\: inst.ant\:Time }}$

➥i(t)=[/tex] $\frac{E.M.F} {R}$

➥ [/tex] $\frac{B o( πa²) ω sin(ωt)}{R}$

➥i = [/tex] $\frac{π}{ 2 ω}$

➥ [/tex] $\frac{B o( πa²) ω}{R}$
