Which of the following creates the emf of the largest magnitude? a. Keeping the direction of the field parallel to the normal to the area of the coil and decreasing the field uniformly from B to zero in 2.0 s. b. Doubling the field value from B to 2B in 2.0 s. c. Keeping the field at value B and rotating the coil so that the normal to the coil's loop area rotates 360o relative to the field direction (i.e., one complete revolution) in 2.0 s. c A changing magnetic field induces an emf of 5.0 V in a single-loop of wire. Suppose the single loop were replaced by one continuous wire wrapped to form a coil of five loops, each with the same size and shape as the original loop, and placed in the same changing magnetic field and with the same orientation as the single loop. What would be the magnitude of the induced emf in the coil? a. 25 Vb. 1.0 V c. 0 V d. 5.0 V a A circular coil of N turns rotates at some frequency in a constant magnetic field and produces an emf. Which of the following will double the emf?
