16. The coil of copper wire (ρ = 16 m • NOM) has a length l = 20 cm, diameter D = 2,0 cm and contains N = 200 turns. Cross-sectional area S = 1,0 mm2. The coil is connected to a source of EMF. After a time t after disabling the EMF source and short-circuiting the coil current is halved in its chain?
