Magnet

The day before in class I’ll see what words students think of when they hear the term magnets. I’ll then explain that every magnet has a north and south pole. Finally I’ll demonstrate what happens when like poles are brought together and what happens when opposite poles are. I will continuously go around the room from group to group to make sure the students are on task and understand what their objectives are. The last ten minutes of class each student will answer 5 simple questions on an exit slip. I’ll start class by demonstrating the activities so the students understand what to do and won’t jump any without understanding it. They’ll also be given instructions that will walk them through step by step. I have put the instructions below in paragraph form so the…

The pre-assessment for the magnet unit was a multiple choice/fill in the blank ten questions written assessment that students were asked to complete to the best of their abilities. This assessment was utilized to assess students’ general knowledge of magnets before beginning the unit. However, since the South Carolina State Standards do not require students to study magnets until second grade, I did not expect students to score high on this pre-assessment. After viewing the data collected…

CHAPTER II. REVIEW OF THE RELATED LITERATURE A. Temporary Magnet Temporary magnets are those that essentially demonstration like permanent magnets when they are inside a strong magnetic field (Jezek, 2015). They are not like permanent magnets when it's not around in a magnetic field because it loses its own magnetism. Temporary magnets cannot remain magnetized on their own (Boyer 2017). Paperclips, press nails, and other comparative things are cases of temporary magnets. Temporary magnets are…

buildings all with the flick of a finger. The Earth itself also happens to be one big magnet, creating a magnetic field, or type of force field, that extends miles beneath the Earth’s surface and into space. Now, split campers into 8 groups of 3 or 4, giving each group two magnets. Have campers hold the magnets close together. What happens? Can they make the magnets stick together or push each other away? Now have them use the magnet to pick up a paperclip. Explain that just like Earth,…

Do magnets have prefered working temperatures? From electronic devices to letters on the refrigerator, magnets exist in almost every room at home, in school, and in the workplace. Some magnets are used as sorters, memory storage, or even just to hang things on the fridge. Yet, how much is even known about these magnets and what they do? Has anyone ever wondered if these magnets have prefered working conditions, like temperature? Or if they work better in hot or cold environments? “In ancient…

Q. Why do wire and a compass work to detect electric currents? A. I’m going to start off with the basics here. A compass points north. Everyone knows that. Why does it point north? Well, all magnets have two “poles” or ends. One end of the magnet is called the north-seeking pole. The north-seeking pole is often abbreviated to north pole or the letter N. The north pole end of a magnet is usually colored red. The other end of a magnet is called the south-seeking pole. The south-seeking pole is…

There were examples of this use in our classroom that students referenced during the class discussion. Additionally, students described magnets being used on their refrigerators to hang their artwork, notes, and/or pictures. Several students discussed toy trains that connected by using magnets. Although these are perfect examples of how many people use magnets in our everyday lives, my desire was for students to learn about ways that magnets make a big impact because of the way they are used…

atoms/elements can be found on the periodic table separately. That magnetic means attractive force to a magnet and, that Iron powder is magnetic. Magnetism is a physical property because it is a reversible property and it can be observed without changing the substance into something new. Solubility is the ability to dissolve in water and salt is able to dissolve in water. Solubility is a physical property because its reversible, it changes in size and shape, and it can be observed without…

works. Fig. 1 shows the parts of the motor. In this motor, there are two field magnets on each side coil with wire. These two field magnets always have opposite polarity. On the middle of the motor there is an armature, two commutators and two brushes. When current flow though the two brushes, one of the brushes touches commutator plate 1 and the other brushes touches commutator plate 2. Then the armature A and armature B turn in to field magnets, because when the current flow though iron that…

Magnetic therapy or magnet healing is a type of alternative medicine that have magnetic fields that generates healing powers towards a large number of diseases or conditions. These electromagnetic fields have been demonstrated to treat slow-healing fractures in the body and have shown good results towards to a few conditions. The website that has claimed to use this magnetic therapy are Skepdic.com. The claim that this complementary and alternative medicine practitioner is making goes…
