Magnets create magnetic fields, which can attract or repel metal objects. Magnets are utilized in motors, circuits, compasses, and can be used in many other applications. They are also used in something called the Gauss Rifle, which can use magnets to launch a projectile at high speed. It is made up of one or more magnet stages, which consists of a magnet and two ball bearings on one side. The number of magnet stages can determine how fast or how slow the projectile can go. It should be noted that this project is not an actual weapon, and will not be able to cause harm to any person hit by the ball bearing.
The Gauss Rifle is a small-scale version of a rail gun. A rail gun uses electromagnets, not normal magnets, to launch a projectile. The…
The science experiment that my partner and I are going to test is, do different brands of batteries affect the electric current of an electromagnet? Electromagnets are magnets that can be powered on and off, they can do simple tasks such as ring doorbells to surgically pull a steel splinter from your eye (Stringer). There are many factors that may affect the way electricity flows throughout metals. For example, the number of coils wrapped around the metal object may affect its magnetic strength.…
closed, there is a force on all electrons (i.e. electric potential difference) which causes them to move (“Physics 16-18”, 2017).
1 Why do the ends of the battery get hot after the wire touches them for an extended period of time?
Electrons traveling through the wire, coiled around an iron nail cause the nail to become a magnet. This device is called an electromagnet. The electrical tape holds each end of the wire against the battery terminals. The battery gets hot because the electrons are…
Grade 9 Term 2 Science Assessment: Electromagnets
Lab Report sheet
Name: Greg Gerald Class: 9A Date: December 3 2015

I. Research Question
How did the amount of volt affect the strength of the electromagnets?
I wanted to know if an electromagnet can be strengthen even more through the increase of its energy.
What is electromagnet?
Electromagnet is a magnet that runs on electricity. Electromagnet is created when a copper wire…
The Great Electro Magnet Race is designed to teach Ms. Rayburn’s fourth grade class about electromagnets and magnetism. The main point for the students to learn will be that certain metals possess an electromagnetic force and can attract other types of metals by their electromagnetic field. Teaching the students about how electromagnets work and what magnetism will surely get them more interested in STEM education. The children need to understand more about engineering design as well as creative…
homemade electromagnetic magnets and permanent
magnets strength on heat and cold temperatures. I'm going to accomplish this by
making three sets of electromagnets and permanent magnets in hot temperature,
room temperature and cold temperatures to see how would they be affected by the
different temperatures its put in. But the dependent variable is on the magnetic field
strength. In the next other paragraphs is research on magnetism and how is it going
to be affected by heat and cold…
Part 2: Magnets and Electromagnets (30 POINTS)
9. Conclusion: Describe at least three magnetism-based concepts that you practiced using the simulations. Be sure to reference the steps in the simulation that indicate what you believed vs. what the simulation showed vs. what science supports. For each concept, be sure to have 1 academic source - meaning 3 different sources. (30 points on turnitin.com)
In these simulations, the unit Gauss (G) was introduced as a new unit of measurement. The unit…
Hydroelectric energy is made from a turbine that turns falling water into mechanical energy; then that mechanical energy is turned into electric energy. This process helps produce electric energy from the kinetic energy of falling water. How does this process involve chemistry? It first begins with the mechanical energy of the water. Mechanical energy is all the energy that is put upon an object. In the case of the hydroelectric generator, the mechanical energy is made from the position of…
An interesting characteristic of this motor is that even when it is not powered, the motor exhibits some magnetic resistance to turning.
• Variable-reluctance (VR) stepper motor — Unlike the PM stepper motor, the VR stepper motor does not have a permanent-magnet and creates rotation entirely with electromagnetic forces. This motor does not exhibit magnetic resistance to turning when the motor is not powered.
The basic construction
Stepper motors consist of a permanent magnetic rotating shaft,…
students of all ages to gain experience around STEM and learn how to creatively think. To get students involved the contest incorporated all kinds of learning. Hands on learners of the class will benefit the most, because the project consists of building electromagnets. However, the audio and visual learners also benefit from the presentation. The Great Electromagnet race is easy to duplicate, because the materials are easy to find, and the materials aren’t expensive.
The cost of the project…
