10 Uses of Magnets Magnets have their lot of applications in the daily life. The major 10 uses of the magnets are as follows: They are used to construct the electrical motors and the generators which convert the electrical energy into mechanical energy and vice verse. They are also used in the speakers which can convert the electrical energy into sound energy.

- All magnets are made of a group of metals called the ferromagnetic metals. These are metals such as nickel and iron. Each of these metals have the special property of being able to be magnetized uniformly.

Physics for Kids Only a few materials have the right type of structures to allow the electrons to line up just right to create a magnet. The main material we use in magnets today is iron. Steel has a lot of iron in it, so steel can be used as well.

Magnet Magnets are made from magnetic materials. These are metals that can be magnetised or will be attracted to a magnet. Most materials are not magnetic, but iron, cobalt and nickel are magnetic. Steel is mostly iron, so steel is magnetic too.

- Electromagnets are used in millions of devices around the world, from hard disk drives and MRI machines, to motors and generators. A motor takes electrical energy and uses a magnet to turn that electrical energy into motion.

- Because the speed of a DC motor is not dependent on the. number of poles, there is great versatility for any constant or variable speed. requirement. In most common DC motors, the magnetic field is produced by high-. strength permanent magnets, which have replaced traditional field coil. windings.

Magnet An electromagnet is made from a coil of wire that acts as a magnet when an electric current passes through it but stops being a magnet when the current stops. Often, the coil is wrapped around a core of soft ferromagnetic material such as steel, which greatly enhances the magnetic field produced by the coil.

- This was just one of the causes of the reasons for the creation of NATO. The Cold War was entering a new phase in the late 40s. In April, Canada, the United States, and nine European nations signed a treaty that created the North Atlantic Treaty Organization. It was the first peacetime military alliance in US history.

Types of Magnets Types of Magnets. Magnets are objects that generate a magnetic field, a force-field that either pulls or repels certain materials, such as nickel and iron. Of course, not all magnets are composed of the same elements, and thus can be broken down into categories based on their composition and source of magnetism.

Force between magnets Force between magnets. Magnets exert forces and torques on each other due to the complex rules of electromagnetism. The forces of attraction field of magnets are due to microscopic currents of electrically charged electrons orbiting nuclei and the intrinsic magnetism of fundamental particles (such as electrons) that make up the material.

Magnet Magnets can be used in scrap and salvage operations to separate magnetic metals (iron, cobalt, and nickel) from non-magnetic metals (aluminum, non-ferrous alloys, etc.). The same idea can be used in the so-called magnet test, in which an auto body is inspected with a magnet to detect areas repaired using fiberglass or plastic putty.

How Magnets Work This is because magnets attract materials that have unpaired electrons that spin in the same direction. In other words, the quality that turns a metal into a magnet also attracts the metal to magnets. Many other elements are diamagnetic -- their unpaired atoms create a field that weakly repels a magnet. A few materials don't react with magnets at all.

- Magnetic starter. A magnetic starter is an electromagnetically operated switch which provides a safe method for starting an electric motor with a large load. Magnetic starters also provide under-voltage and overload protection and an automatic cutoff in the event of a power failure.

Induction motor An induction motor's rotor can be either wound type or squirrel-cage type. Three-phase squirrel-cage induction motors are widely used in industrial drives because they are rugged, reliable and economical. Single-phase induction motors are used extensively for smaller loads, such as household appliances like fans.

The Electric Motor 2.) How Motors Work. Electric motors can be powered by alternating (AC) current or direct current (DC). DC motors were developed first and have certain advantages and disadvantages. Each type of motor works differently but they all use the power of the electromagnetic field. We will talk about the very basic principals of electromagnetic fields in motors before you can move on to the different types of motors.

Magnet Materials that can be magnetized, which are also the ones that are strongly attracted to a magnet, are called ferromagnetic (or ferrimagnetic). These include iron, nickel, cobalt, some alloys of rare earth metals, and some naturally occurring minerals such as lodestone.
