A conducting circular loop is placed in ...

A conducting circular loop is placed in a magnetic field of strength 0.04 T, such that the plane of the loop is perpendicular to the magnetic field. If the radius of the loop begins to shrink at a constant rate of `0.5 mm // s`, then calculate the emf induced in the loop when its radius is 1.5 cm.

To solve the problem of calculating the induced emf in a conducting circular loop placed in a magnetic field, we can follow these steps: ### Step 1: Identify the given values - Magnetic field strength (B) = 0.04 T - Rate of change of radius (dr/dt) = -0.5 mm/s = -0.5 × 10^-3 m/s (negative because the radius is shrinking) - Radius of the loop (r) = 1.5 cm = 1.5 × 10^-2 m ### Step 2: Calculate the area of the loop ...
