An electric field is a vector quantity from which the magnitude and direction of an electric force is determined. The electric force is due to the presence of charged particles.…
What is magnetism? When two pieces of iron are attracted to each other by physical means or electrical means.…
2. Discuss the relationship between electric and magnetic fields. (HINT: Be sure to discuss what happens when electric current is applied to a magnetic field.) The relationship that exists between an electric field and a magnetic field is one of electromagnetic interaction as a consequence of associating elementary particles.…
4. What are the similarities between the compass needle (magnetism) and a test charge (electricity)?…
One magnet can attract other iron, ore and even alloy. But the objects have to be containing one of those materials so it an come together. If two magnets align it it is considered to be called a magnetic field. Compasses are used by magnetic fields coming from the North and South Poles. The way magnets come together is magnetic pulls.…
One of Nikola Tesla’s greatest discoveries was the electric current. Electric currents are used in every technological advance used today like light bulbs, television, etc. during that point of time, it was very impactful. Nothing like it had been discovered yet. “Tesla…
Michael Faraday was the discoverer of the relationship between electricity and magnetism, and that one could not exist without the other. Through his studies he came to believe that there was no such thing as the ether, and he did not believe that matter was a physical substance. Rather, he felt that an infinite amount of invisible lines of force pass through all of space. When these lines intersected they would create matter, which was the very center if the invisible intersecting lines (see diagram 6). From this theory, Faraday felt that light was the motion or vibration of these lines of force.…
The electromagnetic field (EMF) has been a natural part of the earth ever since the beginning of the universe and extends throughout all of space. It is a fundamental form of nature. The most familiar form of the electromagnetic field, to us, is found in sunlight. This electromagnetic field is actually the interaction of both an electric field, which is composed of stationary charges, and the magnetic field which consists of wave like currents.…
Charles Augustin de Coulomb completed a many experiments in which he passed different amounts of electrical charge onto objects and then measured the force between them. He also studied frictional forces. In 1779, he published an important investigation of the laws of friction. In 1785, Coulomb presented his three reports on Electricity and Magnetism, In these reports he described how to construct and use an electric balance, determination of how magnetic and the electric fluids act, and the quantity of Electricity. He used the scientific method to observe and testing these experiments repeatedly. He concluded that the electrical force was in some ways very similar to the gravitational force that Issac Newton had discovered many years earlier. Using the scientific method, he observed that if two electrically charged objects are moved farther away from each other, the force between them gets smaller, just like gravity. Coulomb summarized his finding in a simple relationship know as the Coulomb…
The purpose of this experiment was to look at Michael Faraday and Joseph Henry showed in the 1830’s that a changing magnetic field could cause and induced emf electromotive force = voltage in a circuit. Practically, this means that when a copper pick-up coil is placed inside a solenoid whose magnetic field varies with time, current will flow in this coil even if there is no voltage source physically connected to it. This kind of induced emf is seen everywhere in the modern world in the propagation of light and radio waves, in transformers and generators, or in induction coils that give the spark for the car engine.…
The magnetic field will be perpendicular to the electric field and vice versa Before you begin your lab, you need to form a hypothesis that reflects which material, voltage, and number of winds you think will produce the strongest electromagnet. Record your hypothesis as an if then statement.…
Electromagnetic waves are produced by the vibration of charged particles and have electrical and magnetic properties.…
Earth's magnetic field is one of the world's most complicated features. It started to be observed in 1845 by a scientist named Carl Friedman Gauss (Sarfati). The magnetic field is generated inside of the earth's core and there are many scientists who still debate over how it was first created. There are also many arguments about the many changes that the field has gone through in it's existence. These arguments are mostly either for a young-earth model or an old earth model.…
Magnetic fields are produced by electrical currents, which can be macroscopic current in wires, or microscopic currents associated with electrons in atomic orbits. The magnetic field is force on moving charge in the Lorentz force law. The interaction of magnetic field with charge leads to many practical…
The line integral of the magnetic flux around a closed curve is proportional to the algebraic sum of electric currents flowing through that closed curve; or, in differential form curl B = J.…
