B) Magnetic lines of force are believed to form "closed curves" or to be continuous.
A summary of several discoveries concerning magnetic fields follows: (A) Magnetic lines of force run side by side and do not cross one another.
Magnetic lines of force may be observed by placing a magnet upon the table, then laying upon it a sheet of paper and sprinkling over the latter fine iron filings.
The pressure induced in each of the turns comprising the coil S depends upon the change in the number of magnetic lines through it.
The value of this induced electrical pressure depends upon the number of magnetic lines of force that the conductor cuts in one second.
The intensity of a magnetic flux is expressed by the number of magnetic lines of force in a square centimeter or square inch.
As the property which opposes the flow of electric current in an electrical circuit is called resistance, so the property which opposes the flow of magnetic lines of force in a magnetic circuit is called reluctance.
Power may be lost from this cause even in the metal of the shaft if there be leakage of magnetic lines into it.
Cutting off the current supply in the case assumed leaves the developed magnetic lines or strains unsupported.
The moment we begin the bringing of iron into proximity with an electric conductor conveying current, we provide a better medium for the flow or development of magnetic lines or circuits.
The evolution of magnetic lines, or the opening out of magnetic circuits, goes on at a very rapid rate.
The total number of magnetic lines of force, or magnetic flux, produced in any magnetic circuit will depend on the magnetic pressure (m.
In the upper figure, the air space or "air core" surrounded by the solenoid offers considerable resistance to the passage of magnetic lines, allowing only a small number to pass through.
These lines are called magnetic lines of force or simply lines of force; they show that the medium surrounding a magnet is in a state of stress, the space so affected being called the magnetic field.
The path taken by magnetic lines of force is called a magnetic circuit; the greater part of such a circuit is usually in magnetic material, but there are often one or more air gaps included.
A chain of polarized atomic activity is established in the circuit, similar to the closed circuit of magnetic lines of force, only the latter is static, while the former is dynamic.
When we pass a current of electricity through a wire, magnetic lines of force are thrown out at right angles with the direction of the current.
Magnetism or magnetic linesof force may be developed without the presence of iron.
The above list will hopefully provide you with a few useful examples demonstrating the appropriate usage of "magnetic lines" in a variety of sentences. We hope that you will now be able to make sentences using this group of words.
