An amusement park owner creates a new strength-testing machine. The owner decides to use the induction effect in the Earth's magnetic field B = 10-4 T to measure the initial speed they give the bob: the bob completes a circuit with the sides of the slide, and a voltmeter measures the induced emf. How sensitive must the voltmeter be if the bob is w = 10 cm wide and contestants typically get the bob to rise to heights of h = 10 m? Take note of the magnitude of the induced emf.
