| 单词 | magnetic line of force |
| 例句 | The magnetic lines of force at the surface create many observable effects, including sunspots, which are dark regions where solar plasma cools and emits less light than surrounding areas. How to Watch the Northern Lights and Other Awesome Auroras 2023-10-13T04:00:00Z This simple combination creates magnetic lines of force that corkscrew around the plasma, confining it as a smaller doughnut-within-the-doughnut. Stellar work 2015-10-22T04:00:00Z Things as remote as the magnetic lines of force of an electric current and the stream-lines of a frictionless liquid vortex enter in this way into a peculiar relationship of similarity. Popular scientific lectures 2012-04-24T02:00:17.273Z To remember this, you might compare the magnetic lines of force that arrange the iron filings to the contour strips in a farmer's field. Electricity for the 4-H Scientist Idaho Agricultural Extension Service Bulletin 396, June, 1962 2011-11-18T03:00:30.487Z They followed the direction of the magnetic lines of force, and, forsaking the polar collar of the magnetised sphere, surrounded it like a ruffle. A Popular History of Astronomy During the Nineteenth Century Fourth Edition So that from Maxwell's equations and statements we learn that the magnetic lines of force around every planet, and every satellite in space, move with the planets in their orbits round the sun. Aether and Gravitation He had a proximity detector out, which would pick up any radiation caused by the cutting of magnetic lines of force by any object. A Matter of Importance Magnetic Lines of Force.—It will be noticed that the magnetic lines of force pass through the bar and then go from end to end through the atmosphere. Electricity for Boys The helices on both axles are so connected that, when energized, they induce magnetic lines of force that flow in the same direction through the magnetic circuit. Scientific American Supplement, No. 623, December 10, 1887 The core of this bobbin and the return path for the magnetic lines of force set up in it are composed of soft iron punchings of substantially E shape. Cyclopedia of Telephony & Telegraphy Vol. 1 A General Reference Work on Telephony, etc. etc. That is to say, we shall have such phenomena as magnetic fields, magnetic lines of force, magnetic induction, and the production of permanent magnets by electricity. Aether and Gravitation He seems to have thought that the magnetic lines of force were rendered luminous, or that the light was magnetized; in fact, he was in a fog, and had no idea of its real significance. Scientific American Supplement, No. 275, April 9, 1881 In this set, however, an oscillation transformer is used and as the primary coil of it is included in the closed circuit the oscillations set up in it produce strong oscillating magnetic lines of force. The Radio Amateur's Hand Book Let us look at these three variations from the standpoint of the magnetic lines of force which exist around the earth, and around every planet. Aether and Gravitation The magnetizing force of a given helix is that force which tends to drive magnetic lines of force through the magnetic circuit interlinked with the helix. Cyclopedia of Telephony & Telegraphy Vol. 1 A General Reference Work on Telephony, etc. etc. As the sun is an electro-magnet, therefore, it possesses these magnetic lines of force on all sides, forming a series of magnetic shells. Aether and Gravitation The intensity of a magnetic flux is expressed by the number of magnetic lines of force in a square centimeter or square inch. Cyclopedia of Telephony & Telegraphy Vol. 1 A General Reference Work on Telephony, etc. etc. Because of the inductance, when a current flows through a circuit it causes the electric energy to be absorbed and changes a large part of it into magnetic lines of force. The Radio Amateur's Hand Book The path followed by the magnetic lines of force is called the magnetic circuit, and, therefore, the magnetic circuit of the magnet shown in Fig. Cyclopedia of Telephony & Telegraphy Vol. 1 A General Reference Work on Telephony, etc. etc. |
