An electrical device designed to receive and transmit electromagnetic waves is called an antenna. Antennas are commonly used in radio, television broadcasting, cell phones, radar and other systems involving the use of electromagnetic waves.
Modern innovations in the measurement of flow rate incorporate electronic devices that can correct for varying pressure and temperature (i.e. density) conditions, non-linearities, and for the characteristics of the fluid. An Electromagnetic Flow Meter, also known as a Magmeter, is a tool that measures the rate of flow of a liquid or solids suspended in a liquid through a pipe. Often, such flow meters are used in the wastewater treatment, food processing, and medical industries. They generally rely on the conductivity of the liquid, solution, or slurry that they are measuring as it passes through a magnetic field and generate an electric signal that can be used to measure flow of volume.

Radio antennas are the devices that are used to that send and receive radio signals. Radio waves cover only a small part of the electromagnetic spectrum, which is made up of waves with varying wavelengths. A radio antenna basically consists of long strips of aluminum that changes radio waves, traveling at light speed, into electricity, which is then used to manipulate the electromagnetic field. Radio waves are caught in the air and then filtered into the circuit box.
A water flow meter is designed to measure the amount of water used by consumers both for domestic and industrial purposes. This meter serves as an essential tool in measuring the amount of water used for agricultural purposes too. Related Article Tags: , ,

A Clutch is a mechanical device, which provides driving force to another mechanism, typically by connecting the driven mechanism to the driving mechanism. Its opposite component is a brake, which inhibits motion. Clutches are useful in devices that have two rotating shafts. In these devices, one shaft is typically attached to a motor or other power unit (the driving member), and the other shaft (the driven member) provides output power for work to be done. In a drill, for instance, one shaft is driven by a motor, and the other drives a drill chuck. The clutch connects the two shafts so that they can either be locked together and spin at the same speed (engaged), or be decoupled and spin at different speeds (disengaged).

A radar detector is an electronic device used by motorists to determine whether their speed is being observed or not by a police officer. The objective of a radar detector is to protect the motorist from getting a speeding ticket from the officer who is using a radar gun. Related Article Tags: , , , , , , , , ,
One of the latest innovations in curative jewellery is the q-link pendant. Other items that have been marketed in the past that are similar in concept include magnetic bracelets and necklaces, copper bracelets, and other various types of gemstones that are designed to decrease pain experienced by the wearer. Unlike these, however, the q-link utilizes electromagnetic resonance pulsations to protect the individual wearing it. Related Article Tags: , , , , ,
You should not worry too much if your microwave oven breaks down one day. It is very easy to find microwave spare parts in shops or even online.
Does visible sunlight cause skin cancer? Well, technically no it doesn't. It is the invisible part of the sun's radiation called ultraviolet radiation that tans us when we are out in the sun, generates a sunburn if we are out too long and yes it may cause skin cancer.

The two small words electromagnetic fields or EMF (or one small acronym depending on your direction of thought) describe something that is part of the root cause of many terrible things that are currently plaguing man at this point in time. The new and improved methods of protection from this terrible force that are constantly being invented for us are the only saving graces we have these days. Related Article Tags: , ,

A Proximity Sensor is a sensor able to detect the presence of nearby objects without any physical contact. A proximity sensor often emits an electromagnetic or electrostatic field, or a beam of electromagnetic radiation (infrared, for instance), and looks for changes in the field or return signal. The object being sensed is often referred to as the proximity sensor's target. Different proximity sensor targets demand different sensors. For example, a capacitive or photoelectric sensor might be suitable for a plastic target; an inductive proximity sensor requires a metal target. Related Article Tags: , , ,
Oriental countries such as India and China have traditionally adhered to more alternative treatment methods. These methods are generally based on the understanding that a number of different energies pulse through the human body. Troubles caused to these systems can result in an imbalance causing the individual to be more prone to sicknesses. Related Article Tags: , ,
Electromagnetic fields are very harmful and are found everywhere due to the high amount of products that emits this emf. It is for this reason that we should be aware of these emf emitting products and how to protect us from them. Related Article Tags: , , ,

This means the machine has to be able to put up with more than one workout a day over a course of weeks and years. Related Article Tags: , , , ,
AC Motors are electric motors, these motors are driven by an alternating current. The AC Motors consist of 2 basic parts. The first part: stationary stator having coils that produce a rotating magnetic field with AC current. (Stator is the term to describe the stationery part of a rotor system). The second part is the inside rotor (rotor is the spinning part of a mechanical device), it is given torque by the rotating field and is attached to the output shaft.
