TYPES OF MAGNETIC MATERIALS Paramagnetic materials have a small‚ positive susceptibility to magnetic fields. These materials are slightly attracted by a magnetic field and the material does not retain the magnetic properties when the external field is removed. Paramagnetic properties are due to the presence of some unpaired electrons‚ and from the realignment of the electron paths caused by the external magnetic field. Paramagnetic materials include magnesium‚ molybdenum‚ lithium‚ and tantalum

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

In 1974‚ they started to produce washing machine and refrigerator and after five years‚ they began mass production of microwave ovens. In March 1975‚ Samsung-Sanyo renamed Samsung Electro-Mechanics and merged with Samsung Electronics in 1977. In 1977‚ Samsung started to export their product such as colour television to different countries. Samsung then continue to produce air

A microcontroller (sometimes abbreviated µC‚ uC or MCU) is a small computer on a single integrated circuit containing a processor core‚ memory‚ and programmable input/output peripherals. Program memory in the form of NOR flash or OTP ROM is also often included on chip‚ as well as a typically small amount of RAM. Microcontrollers are designed for embedded applications‚ in contrast to the microprocessors used in personal computers or other general purpose applications. Microcontrollers are used in
