Additionally‚ it seems that electromotor is driven by magnetic force and electromagnetic force has some further applications such as electrostatic instruments and dust catcher. Overall‚ this study plays an important role in both our studies in physics and the development of electromagnetism. Procedure In this typical experiment‚ we used controlling variables method to determine the relationships among how current (I)‚ length of wire (L)‚ and

ADAY‚ MARK JAYSON DL. CEIT-02-301A FUNDAMENTAL FORCES OF NATURE There are four fundamental forces of nature that have been identified the universe‚ namely‚ Weak Force‚ Strong Force‚ Electromagnetic Force and Gravitational Force. They are found to have rather different properties and play central roles in making the universe what it is today. Weak

Most electromagnets consist of wire wound around an iron core. This core is made from soft iron that loses its magnetism quickly when the electric current stops flowing through the wire. Electromagnetism is the branch of physics that studies the relationship between electricity and magnetism. Electromagnetism is based on the fact that (1) an electric current or a charging electric field produces a magnetic field or (2) a charging magnetic field produces an electric field. In 1820‚ the Danish

The Maxwell equations Introduction:- One of Newton’s great achievements was to show that all of the phenomena of classical mechanics can be deduced as consequences of three basic‚ fundamental laws‚ namely Newton’s laws of motion. It was likewise one of Maxwell’s great achievements to show that all of the phenomena of classical electricity and magnetism – all of the phenomena discovered by Oersted‚ Ampère‚ Henry‚ Faraday and others whose names are commemorated in several electrical

NOTE: This paper explains the theory and uses of the electric generator‚ and explains the differences between AC and DC generators. It also includes a glossary and a bibliography. --------------------------------------------------- ELECTRIC GENERATORS In its most basic definition‚ an electric generator is a machine that produces electricity. Generators produce almost all of the electricity used by people. They supply the electric power that runs machines in factories‚ provide lighting‚ and operate

Unit 3 Lesson 5 Electromagnetism Assessment Template 1. Explain what it means when we say a substance is magnetic. (HINT: Be sure to mention the role of the Electrons) If a substance is magnetic‚ we are actually saying that it is able to be acted upon by a magnetic field. When electricity flows through a circuit‚ it creates a magnetic field.When a magnet cuts across a circuit‚ a voltage is produced. 2. Discuss the relationship between electric and magnetic fields. (HINT: Be sure to discuss what

The French physicist Charles Augustin de Coulomb published his first three reports of electricity and magnetism where he stated his law. This publication was essential to the development of the theory of electromagnetism. He used a torsion balance to study the repulsion and attraction forces of charged particles‚ and determined that the magnitude of the electric force between two point charges is directly proportional to the product of the charges and inversely proportional to the square of the distance

Part one: The Lab You will be helping Galileo perform the experiment to determine if objects with different mass fall at the same‚ or different‚ rates in the air and in a vacuum. Before you conduct your experiment‚ you need to form a hypothesis. A hypothesis is a prediction of what you think will happen in the experiment. The hypothesis is a statement that describes “if” a certain set of circumstances are present “then” there will be a specific result that will occur. Record your hypothesis here:

-Faraday- his major contributions were in the fields of electromagnetism and electrochemistry. He explained the basis of magnetic field through his studies on the effects of magnetic field around a conductor which carried Direct Current (DC). In 1831‚ Faraday made one of his most renowned discoveries‚ the principle of electromagnetic induction by using the "induction ring". The electricity was generated by means of electromagnetic effect. This was the first version of an electric transformer. He
