← A long solenoid has 2000 turns per metre. A small coil of 100 turns, each of area 2 cm², sits inside it near its middle, with the same axis. The current in the solenoid is increased steadily at 50 A/s. Take µ₀ = 4π × 10⁻⁷ T m/A. The emf induced in the small coil is closest toA small fish swims at the centre of a round glass bowl of radius 15 cm filled with water (refractive index 4/3), as shown in the figure. Ignore the thin glass wall. Seen from outside, through the side of the bowl, the fish appears to be →
