What is the magnitude of the magnetic field `bar`B at the c. Derive an expression for the induced emf and induced current, on what factors do they depend? The magnitude of the current (I) passing through the coil is 0.4 A. A coil 4.00 cm in radius, containing 500 turns, is placed in a uniform magnetic field that varies with time according to B = (0.0120 T / s ) t+\left (3.00 \times 10^ {-5} T / s^ {4}\right) t^ {4} B = (0.0120T /s)t +(3.00 105T /s4)t4 . A circular coil of 500 turns of wire has an enclosed area of 0. Each turn's radius (r) is 8 cm (0.08 m). A circular coil consisting of 500 turns with an area of 6.0x10-4 m 2 is rotating in a uniform magnetic field.
