The Electromagnetic Force: An Equation

Introduction

This lab is to measure the determinant factors of the size of electromagnetic force that affect with electric and magnetic fields. The electromagnetic force is carried by the photon and is responsible for atomic structure, chemical reactions, the attractive and repulsive forces associated with electrical charge and magnetism, and all other electromagnetic phenomena.
According to Coulomb’s Law, we know electric charges get Coulomb force in the electric field while current receives another applied force, which is Ampere force when it is in a magnetic field. Overall, electromagnetic force is the force that electric charges and current are acted in the electromagnetic field. Electromagnetic force is one of the four fundamental forces in nature. Currently, people can produce strong electromagnetic fields as well as strong electric current due to advanced engineering technologies. Besides, we can obtain a great deal of electromagnetic forces (electrostatic forces) from it. 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 strength of magnetic field (B) affect the size of the electromagnetic force that was exerted on the wire. More precisely, we did three separate experiments to obtain each result by using the same method.

In terms of the relationship between current and the size of the electromagnetic force, we used a digital ammeter to display these current values while we increased the current by

    In an electric field, the displacement of the electrons is related to their charge, mass, and velocity. The purpose of the Thomson experiment is to calculate the mass to charge ratio of the electron. The displacement of the electrons can be observed in this experiment, and the velocity can be calculated from the electric and magnetic fields. The forces produced by the electric and magnetic fields are qE and q  V x B, respectively (where q is the charge of the electron, V is its velocity, E is the electric field, and B is the magnetic field). If the electric and magnetic forces are equal, then the velocity of the electron can be calculated from E and B (V=E/B).…

    The experiment conducted demonstrated correlation between the charge and mass of an electron and the behavior of magnetic fields. The lab was divided into four parts. The first three parts were conducted with a compass that was used to locate the magnetic field lines around a bar magnet, a solenoid and then a pair of Helmholtz coils. As a result of these trials, our observations found evidence that magnetic field lines go from a north magnetic pole to a south magnetic pole. These results were seen in all three magnetic devices. When determining the magnitude of the electric field in the Helmholtz coils, the α value was experimentally determined to be 8.522×10-4 T/A and this value differed by 9.378% from the expected α value of 7.791×10-4 T/A. Lastly, in the fourth part of the experiment, the charge to mass ratio was calculated by bending an electron beam in side an e/m tube with the Helmholtz coils and came out to be 1.158×1011 C/kg, with a 34.17% error from the expected value 1.759×1011 C/kg.…

    Hypothesis: When there is a flow of moving electrons, a magnetic field is created. We use the equation F = NIlB (Force = Number of coils x Current x Length of Wire x Magnetic Field Strength) to work out the magnetic force produced in a wire when there is an electric current present. Using this equation we can see that increasing the length of the wire (amount of coils) gives a larger force. So increasing the amount of coils in an electromagnet gives a larger EMF.…

    Electromagnetism is one of the four fundamental interactions of nature. It is the force that causes the interaction between electrically charged particles; the areas in which this happens are called electromagnetic fields. It was discovered when it was observed that a copper wire carrying an electric current can magnetize pieces of iron or steel near it. An electromagnet is made from two components, a solenoid, and a ferromagnetic material. The solenoid is an insulated…

    This experiment clearly demonstrated how Ampere’s Law relates the magnetic field to the current using the relationships stated in the formula B= μ0I2πr. This relationship allowed to the experiment to calculate the value of permeability of free space in order to verify the relationship that is outlined in Ampere’s Law. This lab also allowed us to measure magnetic field strength as a function of the distance measured perpendicularly from a long current-carrying wire.…

    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 lab is to examine the motion of an electron, when it encounters a constant magnetic and electric field. We will also observe when the electric field and magnetic field will cancel each other out. This will lead to the electron having no net force acting upon it. By adjusting the values for the magnetic and electric fields, we will be able to check the different paths the electron follows. From this data we will be able to calculate the charge-to-mass ratio. Then, using the accepted value, we can calculate the percentage error.…
