Given data:
- Number of turns in the coil (N) = 200
- Size of the coil (l x b) = 0.3 x 0.1 m
- Magnetic field intensity (B) = 0.005 Wb/m²
- Frequency of rotation (f) = 1800 rpm

Formula:
The induced emf (ε) in a rotating coil is given by the formula:
ε = NABωsin(ωt)

where,
A = Area of the coil = l x b
ω = Angular velocity = 2πf

Calculations:
1. Area of the coil:
A = l x b
A = 0.3 x 0.1
A = 0.03 m²

2. Angular velocity:
ω = 2πf
ω = 2π x 1800/60
ω = 376.99 rad/s

3. Maximum value of induced emf:
εmax = NABω
εmax = 200 x 0.03 x 0.005 x 376.99
εmax = 11.27 V

Answer:
The maximum value of the induced emf is 11.27 V.
