A generator is designed to produce a maximum emf of 120 V while rotating with an angular speed of 3600 rpm. Each coil of the generator has an area of 0.033 m2. If the magnetic field used in the generator has a magnitude of 0.050 T, how many turns of wire are needed?
A generator is designed to produce a maximum emf of 180 Vwhile rotating with an angular speed of 3300 rpm . Each coilof the generator has an area of1.9×10−2 m2. If the magnetic field used in the generatorhas a magnitude of 4.5×10−2 T , how many turns of wire are needed?
You are designing a generator to have a maximum emf of 15 V. If the generator coil has 100 turns and a cross-sectional area of 7×10−2 m2, what should be the frequency of the generator in a uniform magnetic field of 5×10−2 T?
A generator almost always contains a coil of wire inside a magnetic field. The coil shown below has N turns and a radius of R. It is rotating in a magnetic field of strength B at an angular frequency o. This means that the angle between the area vector of the coil and the magnetic field is = wt. х a. What is the induced emf in the coil as a function of time? b. If the left side of...
