B=0 (μ0 i1/2 π y)=(μ0 i θ/4π x) c=(1/√μ0E0)

Q. Magnetic field induction at the center of a circular coil of radius 5cm and carrying a current 0.9 A is ( in S.I. units) ( $\in_{0}$ = absolute permittivity of air in S.l. units: velocity of light= $3 \times 1 0^{8} m s^{- 1}$ )

$\frac{1}{\in _{0} 1 0 ^{16}}$

$\frac{1 0 ^{16}}{\in _{0}}$

$\frac{\in _{0}}{1 0 ^{16}}$

$1 0^{16} \in_{0}$

$B = 0$
$\frac{μ _{0} i _{1}}{2 π y} = \frac{μ _{0} i θ}{4 π x}$ c $= \frac{1}{μ _{0} E _{0}}$
