What is the magnetic field strength?
The power of the
magnetic field is an effect that the magnetic field develops or acts on a charged particle, such as a molecule, when passing through this field. These forces exist whenever an electrically charged molecule near a magnet, or when electricity passes through a wire or coil. The magnetic field strength can be used to perform electric motors and to analyze the chemical structures of materials due to the way the particles react to it.
When the electric current passes through the wire, the flow of electrons creates a magnetic field and creates a force that can affect other materials. A common example of the magnetic field force is an electric motor that uses a moving rotor with wires around it, surrounded by a stator with other coils. When electrical current is applied to the stator coils, the magnetic field creates and the force of this field creates a torque that moves the rotor.
The magnetic field force can be described using what is called the wone on the right hand. A person can direct his thumb, index notbo first finger and second finger in three different directions, often called X-, Y, and Z axes. Each finger and thumb should be 90 degrees together, so if the person shows the index finger up, the second finger shows left and thumbs point directly to the person.
Using this finger arrangement each finger displays the directions of the electric flow (index finger), magnetic field (second finger) and the resulting magnetic field (thumb). When the four fingers of the hand are curled towards the palm, it shows the direction of the magnetic field with the thumb continues to indicate the direction of force. The use of the right right is an easy way to learn about magnetic fields to see the effects of current and forces that result in.
Magnetic fields can be useful in the laboratory for material analysis. If the material needs to be identified or divided into its molecular components, the sample may be ionized, which changes the material into gas with positive or negativeElectric charges. This ionized gas is then passed through a strong magnetic field and exits the collection area.
The weight or weight of each ionized particle of the test sample reacts differently to the magnetic field and the particles are slightly bent from the straight direction. The collection device registers where each particle hits a detector and computer software can identify the molecule from how it interacts with the fields. One type of device using this technology is called a mass spectrometer and is widely used to help identify unknown substances.
Another use of magnetic fields to change in ionized materials is the particle accelerator. At the end of the 20th century, the largest accelerator of the Buiv particle at that time is located on the edge of Switzerland and France, with 17 miles (27 kilometers) accelerator deep below the ground in a large loop. The device took advantage of the magnetic field strength to quickly accelerate charged particles into a loop where the next field accelerated or acceleratedLa charged particles.
When the high -speed particles circled the large collector, they were controlled by other inspections of the magnetic field and sent to collisions with other materials. This equipment was created to test high -energy collisions similar to those observed in the sun or other stars and during nuclear reactions. The position of the underground was used to prevent particles from disrupting the test results, as the rocks of the rock above the accelerator absorbed high -speed energy and ions.
