12 Uses Of Electromagnet

You will come to know about the application of electromagnet uses in detail. We will discuss here how they are useful and applied in the processes, types of equipment, and devices. Let us begin and understand the uses of electromagnet in the following.

  • Headphones And Loudspeakers

Magnets are an important part of the design of most headphones and loudspeakers as they depend on electromagnetism applications to work efficiently as transducers. Many speakers and their prototypes would be impractical to build without magnets. Speakers are energy transducers, converting electrical energy audio signals into mechanical wave energy sound waves. To produce sound, many speaker drivers use electromagnetism to convert the alternating current voltage of the audio signal into a particular movement within a magnetic field. 

In the speakers, the moving-coil drivers are commonly recognized as the most common form of speaker transducer. The most common uses of electromagnet are done in the drivers of loudspeakers, studio displays, automotive audio systems, external microphones for computers or phones, and so on.

  • Relays And Valves

A relay is a type of switch that is activated and deactivated by an electromagnet. This is a magnetic relay valve. using a magnet a power supply means for energizing and de-energizing the magnet at preset temperatures, a valve stem, the main armature fixed to said stem and usually beyond the area of the magnet, and a relay armature normally inside the same field. Much of the time, a low voltage or current is used to switch higher voltages or currents, which can be electromechanical or entirely electrical. The electromagnetic controls are powered by electricity that is generated by general uses of electromagnet fields.

  • Generators And Motors

The most common use of magnetic force on current-carrying wires is electric motors, which transform electrical energy into mechanical energy. Motors are created up of wiring loops in a magnetic field. As current flows through the loops, the magnetic field exerts a force on the loops, forcing a shaft to spin. A generator is a system that transforms mechanical energy into electrical energy. It is one of the most important 10 uses with application of electromagnets in our daily life. Motors and generators are essentially the same units that can operate in two opposing modes.

However, there are the two modes of the motor and generator that work in opposite ways. It is said that a motor is a unit that turns in one direction, and a generator is a system that turns in the opposite direction.

  • Electric Buzzers And Bells

An electromagnet that is made up of coils of insulated wire wrapped around circular iron poles, is located in an electric bell. When an electric current passes through the coils, the rods act as a magnetic field and attract a clapper that is attached with a piece of iron. The clapper taps the bell, causing it to ring. The uses of electromagnetic coils include the same principle as seen in the electric buzzers.

  • MRI Machines

Magnetic resonance imaging (MRI) machines do the uses of electromagnet. It is a scanning tool used to create accurate photographs of the human body. The scan generates photographs of areas of the body that X-rays, CT scans, and ultrasound cannot see as well. It uses a high magnetic field and radio waves to produce images of parts of the body that X-rays, CT scans, and ultrasound cannot see as well. They can also be known as nuclear magnetic resonance imaging (NMRI).

MRIs use powerful magnets to create a high magnetic field that causes protons in the body to align with it. When a radiofrequency current is pulsed through the patient, it activates the protons. This is allowing protons to spin out of alignment and contract against the magnetic field’s pull.

  • Particle Accelerators

A particle accelerator is a system that uses electromagnetic fields to accelerate charged particles at high speed and energies. Along with the acceleration of the particles they are also l stored in well-defined beams. These are the two uses of electromagnet in a particle accelerator. Large accelerators are used in fundamental particle physics experiments. Electric fields are used in particle accelerators to accelerate and increase the energy of a beam of particles that are directed and centered by magnetic fields.

  • Mass Spectrometers

Magnetic sector mass spectrometers use a bending magnet as ions or atoms touch the magnet, they are pushed to bend, and the light ions bend sharper than the heavy ions, resulting in a rainbow-like spectrum. This is what are some uses for electromagnets in mass spectrometers. The magnetic fields will deflect atoms if the atom is first converted into an ion. In a mass spectrometer, the magnetic field impacts electrically charged particles but not the electrically neutral particles. 

  • Data Storage Devices

Magnetic storage is a form of non-volatile memory that uses various patterns of magnetization in a magnetizable material to store data. One or more read/write heads are used to access the data. Storing data is among the 10 uses of electromagnets in ebook devices and phones is stored in the electromagnetic format as bytes and bits. The computer hardware also contains a magnetic tape that acts on the electromagnetism principle. The storing of data on a magnetized medium is known as magnetic storage or magnetic recording. Floppy disks, magnetic tape, and magnetic stripes on credit cards are also types of magnetic storage media.

In magnetic storage media, mainly hard disks, are commonly used to store both computing data and audio and video signals. Magnetic storage is preferred in the field of computing, whereas magnetic recording is most widely found in the field of audio and video processing.

  • Induction Cooker

Induction cooking is one of the uses of electromagnets in everyday life that works on the principle of electromagnetism. This helps to convert cooking pans into cookers, generating heat energy inside the pan itself rather than firing it in from the outside. It is allowing food to be cooked more rapidly and efficiently by using less energy. The technology’s strength and accuracy are derived from an electric field under the glass cooktop base. This passes current directly to magnetic cookware, allowing it to heat up. 

Induction removes the intermediate stage of heating a burner and then passing heat to the container. The induction cooker electrical induction to heat a cooking vessel rather than thermal conduction from a flame or an electrical heating device. A ferromagnetic metal, such as cast iron or stainless steel, must be used in the cooking pot.

  • Magnetic Locks

In magnetic locks, applications of electromagnetism have been used to power the whole locking mechanism. When the magnet is energized, it forms a bond with the armature and locks the door. To allow entry or egress, a switch to de-energize the magnet must be provided. The bolt locks the door while the electric force unlocks the magnet. Since the electromagnet and armature’s mating region is comparatively broad, the magnetic flux’s force is high enough to hold the door locked even under tension.

Real life uses of electromagnet locks are widely used in hotels, offices, and residential buildings because they are safe, dependable, and simple to install due to the limited number of components.

  • Transformers

An electric transformer is a system that changes the voltage of an electric current by using electromagnetic induction. It happens when a magnetic field and an electric conductor, such as a wire coil, shift relative to each other. You might have heard in the physics problem of the most powerful electromagnet in the world uses 24 MW of power which is based on the transformer. The voltage may be increased or reduced with help of a transformer. The method of producing current with a magnetic field is known as electromagnetic induction. Other types of transformers exist for particular possible uses of an electromagnet such as audio, electrical, and instrumentation. 

All of these transformers operate on the theory of induction in alternating current power, but their structure varies to match their various functions. These functions can include voltage balancing or specifically down-converting high voltage to allow sensitive instruments to read current.

  • Agriculture

Some of the uses of electromagnetic radiation in agriculture are checking and testing soil and water. Some instruments work on electromagnetic induction which is used for fast measurement of the electrical conductivity of the soil. They will supply data for land resource assessment, soil function, salinity assessment, precision cultivation, etc. This will help to improve agriculture and the techniques for cultivation.
