**Physics Problem: Induced EMF in a Circular Coil**

A 26-turn circular coil of radius 4.20 cm and resistance 1.00 Ω is placed in a magnetic field directed perpendicular to the plane of the coil. The magnitude of the magnetic field varies in time according to the expression \( B = 0.010 \, t + 0.040 \, t^2 \), where \( B \) is in teslas and \( t \) is in seconds. Calculate the induced emf in the coil at \( t = 5.20 \) s.

**Induced EMF:**
The answer box is provided for the induced emf calculation, with the unit mV (millivolts).
