Magnetism (What is it and how does it work?)
Give your kid a little magnet and let them go through the house and see how many things and what type of things they can pick up, using only the magnet.

Let's start at the beginning...

What is magnetism?
Magnetism is a force that is created by electric current that is most likely caused by the moving electrons.

What is magnets?
A magnet has two end that we call poles, a north pole/north-seeking pole or a south pole/south-seeking pole. The north pole of a magnet attracts the south pole of a second magnet, but the north-pole of one magnet repels the north-pole.

    In the twentieth century the medical field has seen many changes. One way that hospitals and nursing specifically has changed and implemented the changes is by pursuing accreditations, awards, and recognitions. The purpose of this paper is to understand Magnet Status and the change required by hospitals to achieve it.

    Magnetic fields are frequently compared to gravitational fields. Gravitational fields cause a curvature of space-time. That curvature of space-time provides a mechanism for the gravitational attraction between masses. A magnet also causes a curvature of space-time. In fact a magnet can cause space-time curvature in several distinct ways.

    1226 Words  | 3 Pages

    Electromagnetism is the study of the relationships between magnetism, and electricity. It was found by Hans Oersted, that when an electric current flows in a wire, the current creates a magnetic force around this wire. It is also known that a solenoid produces a considerably large amount of magnetic force when a current flows through it (diagram 1.1 ). By using a solenoid and some small, light rings of copper and aluminum, it is said that the ring when placed over the solenoid when current is flowing will 'jump' up and sometimes levitate if the force of the magnetic field equals that of the earth's gravitational force.

  • Magnets and Electromagnets

    1030 Words  | 3 Pages

    A magnet, defined in the Merriam-Webster dictionary, is classified as “a piece of iron (or an ore, alloy, or other material) that has its component atoms so ordered that the material exhibits properties of magnetism, such as attracting other iron-containing objects or aligning itself in an external magnetic field” (insert citation for google). This definition is saying that a magnet contains a magnetic field and it can attract other objects with like properties of that magnet so that they match up with one another creating a constant hold. Magnets were discovered over 2,000 years ago when the Greeks found a mineral that joined with like objects made of iron. This mineral was discovered in a city called Magnesia, so the Greeks named it magnetite (insert saxon citation).

    The relationship between electricity and magnetism is that each phenomenon generates a field. Electric fields can be pictured by thinking in terms of gravitational forces. Where, any two objects have a gravitational force on one another. Any two electric charges have a force between them (either repelling, or attracting depending on polarity). These electric fields are vector forces, with size and direction at each point in space....

    It’s the magnetic field that extends from the earth’s interior to where it meets the solaria stream of charged particles emanating from the sun. The magnetic field resembles the field of a large bar magnet near its center or that due to a uniformly magnetized sphere. Its origin is thought to be generated deep down in the earth’s core.

    Electric currents produce magnetic fields, they can be as small as macroscopic currents in wires, or microscopic currents in atomic orbits caused by electrons. The magnetic field B is described in terms of force on a moving charge in the Lorentz force law. The relationship of magnetic field and charges leads to many practical applications. Magnetic field sources are dipolar in nature, with a north and south magnetic pole. The magnetic field SI unit is the Tesla, it can be seen in the magnetic part of the Lorentz force law F magnetic = qvB composed of (Newton x second)/(Coulomb x meter). The smaller magnetic field unit is the

    The Earth’s magnetic field is a major component to exploring the earth. The north and the south poles have always been a guide for travelers. Using compasses, the direction of the north pole and the south pole has always been provided by the magnetic force of the magnetic field. What many people do not know though is the earth’s magnetic field provides way more than that. The magnetic field, also known as the magnetosphere, protects us from all kinds of harmful substances. Some of these substances include solar wind and harmful radiation from the sun. The magnetosphere also protects the atmosphere, which protects us.
