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
