    (20 pts) You are studying the magnetic gyro wheel toy that you just gave your 10- year-old cousin. You are holding it vertically and are considering motion along one of the "arms” as shown in the drawing to the right. The magnetic gyro starts from point A with an angular velocity, o, of 2 revolutions per second and is 0.2...

    Mass SpectrometerJ. J. Thomson is best known for his discoveries about the nature of cathode rays. Another important contribution of his was the invention, together with one of his students, of the mass spectrometer. The ratio of mass m to (positive) charge q of an ion may be accurately determined in a mass spectrometer. In essence, the spectrometer consists of two...

    One long wire lies along an x axis and carries a current of 30 A in the positive x direction. A second long wire is perpendicular to the xy plane, passes through the point (0, 4 m, 0), and carries a current of 38 A in the positive z direction. What is the magnitude of the resulting magnetic field at...
