A compass needle is not always balanced parallel to the Earth’s surface, but one end may dip downward. Explain.
The compass needle is not always balanced parallel to the Earth’s surface.
Answer to Problem 1Q
The Earth’s magnetic field lines are not parallel to the surface of the Earth
Explanation of Solution
The Earth's magnetic field is not always parallel to the surface of the Earth. It may have a component perpendicular to the Earth’s surface. This is because the earth is not a uniform circle.
The compass tends to line up with the local direction of the magnetic field, so one end of the compass will dip downward.
Conclusion:
The Earth’s magnetic field lines are not parallel to the surface of the Earth

- If a cosmic ray proton approaches the Earth from outer space along a line toward the center of the Earth that lies in the plane of the equator, in what direction will it be deflected by the Earth’s magnetic field? What about an electron? A neutron?arrow_forwardImagine 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?arrow_forwardThere 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?arrow_forward
- An electron moves in a circular path perpendicular to a constant magnetic field of magnitude 1.00 mT. The angular momentum of the electron about the center of the circle is 4.00 1025 kg m2/s. Determine (a) the radius of the circular path and (b) the speed of the electron.arrow_forwardIntegrated Concepts (a) Show that the period of the circular orbit of a charged particle moving perpendicularly to a uniform magnetic field is T = 2(m/(qB). (b) What is the frequency f? (c) What is the angular velocity ( Note that these results are independent of the velocity and radius of the orbit and, hence, of the energy of the particle. (Figure 22.64.] Figure 22.6-4 Cyclotrons accelerate charged particles orbiting in a magnetic field by placing an AC voltage on the metal Dees, between which the particles move, so that energy is added twice each orbit. The frequency is constant, since it is independent of the particle energyThe radius of the orbit simply increases with energy until the particles approach the edge and are extracted for various experiments and applications.arrow_forwardAround the geographic North Pole (or magnetic South Pole), Earth’s magnetic field is almost vertical.
