• Induced EMF = (change in Magnetic Flux Density × Area)/Time.

Or,

• Induced EMF = (change in Magnetic Flux Density × length × breadth)/Time.

Here,

We use speed = Distance/time. We get:

EMF = Magnetic flux density x Width x Speed.

• Magnetic flux - 5.0×10⁻⁵ NA⁻¹ m⁻¹
• Width - 2m
• Speed - 1.50m/s

Substitute in formula. Do check if the units are the same.

➥ EMF = 5.0 × 10⁻⁵ NA⁻¹ m⁻¹ × 2 m × 1.5 m/s

➥ EMF = 15 × 10⁻⁵ Volts.
