production of certain niche MRAM products over the next several years. WHAT IS MRAM? MRAM is a non volatile random access memory which uses magnetic storage and Magneto resistance(MR) to read the stored data. Magneto resistive material is a resistor made of common ferromagnetic material which will change in resistance in the presence of a magnetic field. The magneto resistive property gives a small but sufficient signal to

appliances‚ and toys in every room in your home. They are a very important and vital part of modern life. Have you ever played with magnets before? If so‚ you are well on your way to understanding how simple electric motors work. Magnets have a magnetic field with a north pole and a south pole. If you play with two magnets and try to push the north poles of each magnet together‚ the magnets will not go together. They will repel each other. The same thing happens if you try to push two south poles

dry type magnetic separator is commonly used iron ore and manganese ore beneficiation equipment. It is the mainstream strong magnet separator‚ which is specialized in processing dry magnetic minerals. The wet type magnetic separator use liquid diluents to improve separation efficiency. The dry type magnetic separator requires that the material must be dry‚ and can move freely between the particles. Or it will affect the separation result‚ and even cannot separate materials. The magnetic system of

An electromagnet is a type of magnet in which the magnetic field is produced by electric current. The magnetic field disappears when the current is turned off. Electromagnets are widely used as components of other electrical devices‚ such as motors‚ generators‚ relays‚ loudspeakers‚ hard disks‚ MRI machines‚ scientific instruments‚ and magnetic separation equipment‚ as well as being employed as industrial lifting electromagnets for picking up and moving heavy iron objects like scrap iron.

Electrical technology – assignment 4 Properties of electrical materials and Effective use of technology P.5. Describe the properties and a typical application of a solid and a liquid or gas electrical conductor. A conductor is a material that allows free movement of electrons and therefore allows easy flow of electricity. Most conductors are metals. A common metal used as a conductor in electrical technology is aluminium. It is used quite a lot as it cheap‚ lightweight and in abundance compared

Departmentalization is the process of grouping specialized jobs into logical units (Griffin‚ 2013). When deciding what departmentalization type is best for a company managers are faced with several decisions/dilemmas. The following should be considered: • The products they produce • Who their customers are • Where their customers are located Once the above considerations has been taken‚ a manager can then look at the advantages and disadvantages to the different types of departmentalization

One thing that uses magnetic fields is the electric motor‚ which is used in many household appliances‚ such as electric fans‚ microwave ovens‚ and other small appliances. In this instance the electric motor has an electric current‚ giving it also this magnetic field. An electric motor converts electricity into mechanical motion. Most electric motors work by electromagnetism‚ but motors based on electrostatic forces also exist. The overarching concept is that a force is generated when a current-carrying

Investigatory Projects in Physics | Repulsorlifts as a Method of Stable Magnetic Levitation | Repulsorlifts were used in the study to find out if they can be used to replace the wheels of a conventional car. It was hypothesized that it will be able to lift a car using magnetic repulsion forces. The different magnets were tested individually with the usual tests for magnetic strength‚ size‚ and temperature increase‚ which were done in the preliminary testing. The prototype road and car were
