They are a component in Transformers.
yes
creating earth's magnetic field:)
its responsible for Earth's magnetic field.
Silver is a not magnetic metal - the most highly magnetic metal is iron - so no unless the cores of the coins are iron
The price of 5 cores in pounds can vary greatly depending on the type of cores being referred to. Cores could refer to computer processing units, magnetic cores used in electronics, or geological cores obtained from drilling. It would be helpful to provide additional context to accurately determine the cost of 5 cores in pounds.
possibly because the magnetic 'direction' is one way or the other - metaphorically "on" or "off" - 'zero' or 'one'
Thin metal laminations are used to minimize the magnetic flux eddy current loss in the stator cores of high-speed, high-performance induction motors.
Iron is a better core material than steel for applications that require high magnetic permeability due to its higher saturation magnetization. This makes iron cores more efficient in transferring magnetic fields. Additionally, iron cores have lower hysteresis losses compared to steel cores.
The magnetic circuit concept simplifies the analysis of magnetic fields in transformers and machine cores by allowing engineers to model the magnetic path as a series of magnetic components, similar to an electrical circuit. This approach helps in calculating parameters such as magnetic flux, reluctance, and magnetomotive force, enabling the optimization of core materials and geometries for efficiency. By understanding the magnetic circuit, designers can minimize losses, enhance performance, and ensure that the core can handle the required magnetic flux without saturation. Ultimately, this leads to improved reliability and efficiency in electrical devices.
Examples of magnetic circuits include transformers, inductors, and magnetic cores in motors and generators. These circuits consist of magnetic materials that guide the flow of magnetic flux from one component to another, allowing for efficient transfer of energy and operation of electrical devices.
Pulsars are formed from the cores of massive stars that have exploded in supernovae. During the collapse, their magnetic fields get amplified to extremely high levels due to conservation of magnetic flux. This results in pulsars having large magnetic fields.
Because of the continuous flow of iron and nickel through the inner and outer cores of Earth.
