There are regions where the magnetic field of earth is almost perpendicular to the surface of Earth. What difficulty does this cause in the use of a compass?
(Indicates a review question, which means it requires only a basic understanding of the material to answer. Questions without this designation typically require integrating or extending the concepts presented thus far.) Describe the three basic interactions between electricity and magnetism.
Imagine you have a compass whose needle can rotate vertically as well as horizontally. Which way would the compass needle point if you were at the Earths north magnetic pole?
Around the geographic North Pole (or magnetic South Pole), Earth’s magnetic field is almost vertical. If an airplane is flying northward in this region, which side of the wing is positively charged and which is negatively charged?
Is the Earth's magnetic field parallel to the ground at all locations? If not, where is it parallel to the surface? Is its strength the same at all locations? If not, where is it greatest?
The Earths Van Allen belts (Fig. 30.34) are a natural magnetic bottle, trapping cosmic rays that spiral back and forth between the North and South Poles. Use the shape of a cosmic rays path to describe the variation in the magnetic field strength.
Volcanic and other such activity at the mid-Athletic ridge extrudes material to fill the gap between separating tectonic plates associated with continental drift. The magnetization of rocks is found to reverse in a coordinated manner with distance from the ridge. What does this imply about the Earth's magnetic field and how could the knowledge of the spreading rate he used to give its historical record?
If a charged particle moves in a straight line through some region of space, can you say that the magnetic field in that region is necessarily zero?
An electron moving at 4.00103 m/s in a 1.25-T magnetic field experiences a magnetic force of 1.401016 N. What angle does the velocity of the electron make with the magnetic field? There are two answers.
A mass spectrometer is being used to separate common oxygen16 from the much rarer oxygen18, taken from a sample of old glacial ice. (The relative abundance of these oxygen isotopes is related to climatic temperature at the time the ice was deposited.) The ratio of the masses of these two ions is 16 to 18, the mass of oxygen-16 is 2.661026kg, and they are singly charged and travel at 5.00106m/s in a 1.20T magnetic field. What is the separation between their paths when they hit a target after traversing a semicircle?
Why do iron filings show magnetic field patterns?
Calculate the magnetic force on a hypothetical particle of charge 1.010l9C moving with a velocity of 6.0104im/s in a magnetic field of 1.2kT.
