Why radial magnetic field?
A radial magnetic field is often used in applications where the magnetic field needs to be concentrated in a particular area, such as in electric motors or generators. By having a radial magnetic field, the magnetic flux can be directed efficiently through the device and produce the desired output. Additionally, a radial magnetic field can minimize energy losses and improve the overall performance of the device.
How inductor produces magnetic field?
An inductor produces a magnetic field when current flows through it, according to Faraday's law of electromagnetic induction. The magnetic field forms around the inductor's coil due to the flow of electricity, creating a magnetic flux that can store energy in the form of magnetic field lines. This magnetic field is what allows inductors to store energy and resist changes in current flow.
Which device that indicate the direction of the magnetic flux?
A compass is a device that indicates the direction of the magnetic flux. It aligns with the Earth's magnetic field and points towards the magnetic North Pole.
What layer produces a magnetic field around the earth?
The outer core of the Earth, composed mainly of molten iron and nickel, produces the magnetic field that surrounds the Earth. The movement of this liquid metal creates electric currents, generating the planet's magnetic field.
Does wrapping a metal bar inside the coils decrease the field strength of a electromagnet?
No, wrapping a metal bar inside the coils of an electromagnet can actually increase the field strength. The presence of the metal core enhances the magnetic properties of the coil, resulting in a stronger magnetic field. This configuration is known as a ferromagnetic core electromagnet.
What device produces a magnetic field froma moving electrical charge?
magnet
Does lightning produces magnetic field?
Yes, The movement of electrical charges produces a magnetic field
Which layer of the earth produces its magnetic field?
The earth's outer core produces the magnetic field.
What is an electrical current that produces a magnetic field?
The deflection of a magnetic compass in the presence of an electric current, is evidence that an electric current produces a magnetic field.
What is evidence that an electrical current produces a magnetic field?
The deflection of a magnetic compass in the presence of an electric current, is evidence that an electric current produces a magnetic field.
Which device does not have a magnetic field?
the device is a dedle on compass
What device is made from a coil of wire that carries a current and produces a magnetic field?
These devices are called generators, alternators, magnetos, or dynamos. These devices produce electrical energy from mechanical energy. The opposite is a motor which produces mechanical energy from electrical energy.
What is definition of paramagnetic and dimagnetic materials?
A dimagnetic material produces a magnetic field that opposes an external field. A paramagnetic materia, on the other hand, produces a magnetic field that increases an external field. Dimagnetism and paramagnetism are induced when an object is placed in a magnetic field.
What does moving electricale charge produce?
It produces a magnetic field.
What energy produces a magnetic field?
electric energy
An electric current produces a magnetic field?
Yes.
What is a coil of wire that when carrying a electric current produces a magnetic field?
No field
