a motor
The Earth's magnetic field is generated by the motion of molten iron and nickel in its outer core. This motion creates electric currents, which in turn produce a magnetic field that extends into space and surrounds the planet.
The stator of an electric motor contains coils of wire that generate a magnetic field when an electric current passes through them. This magnetic field interacts with the permanent magnets on the rotor, causing them to repel each other and create motion in the motor.
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.
The outer part of Earth's magnetic field is known as the magnetosphere. This region is shaped by the solar wind, a stream of charged particles from the Sun, interacting with Earth's magnetic field. The magnetosphere helps protect our planet from harmful radiation and solar wind.
The part of an atom responsible for producing magnetic fields is the electrons. Electrons possess a property called "spin," which generates a magnetic moment. When electrons move around the nucleus of an atom, their spinning motion creates a magnetic field. This magnetic field can interact with other magnetic fields to produce various magnetic effects.
A magnetic field is induced in an region of space in which and electric field is changing with time.
An electromagnet uses an electromagnetic field to generate a magnetic field when an electric current flows through it.
Part of the electromagnetic spectrum can be detected by eye, and we call that bit "light". The thing about electromagnetic radiation is that a varying magnetic field causes a (varying) electric field (that's how power stations make electric current) and a varying electric field causes a (varying) magnetic field. So electromagnetic radiation is what you get when a varying electric field creates a varying magnetic field which in turn contributes the varying electric field. The whole thing then appears as bundled varying electric and magnetic field wave system which propagates at the velocity of light, That is why it is called electromagnetic. There are no magnetic poles or electric charges in it, and it can travel through a vacuum.
The armature of an electric motor is the part that repels the poles of the permanent magnets due to the flow of electric current through the conductors in the armature, creating a magnetic field that interacts with the magnetic field of the permanent magnets to produce motion.
The Earth's magnetic field is generated by the motion of molten iron and nickel in its outer core. This motion creates electric currents, which in turn produce a magnetic field that extends into space and surrounds the planet.
Permeability
field coils generally refer to the electromagnetic coils on the stator ( the stationary part of an electric motor ). these generate the magnetic field(s) necessary to put the rotor ( the rotating part of the motor ) into motion.
The earth as a single object has a magnetic field. If Uruguay is part of the earth, it shares the earth's magnetic field.
Magnetic field lines are closest together at the poles of a magnet, where the magnetic field is strongest. This is where the magnetic force is most concentrated.
The stator of an electric motor contains coils of wire that generate a magnetic field when an electric current passes through them. This magnetic field interacts with the permanent magnets on the rotor, causing them to repel each other and create motion in the motor.
An electro-magnetic field is made up of both an electric and a magnetic field. And they both consist of photons. The two fields are orthogonal in direction. Which means their wave directions are perpendicular to each other. EMF's are produced each and every time the momenta of electrons changes. So when the speed, direction, or both of electrons change, EMF is created and the electric field is part of that EMF.
If you are referring to a magnet as an object that possesses a permanent magnetic field, then yes. There are three circumstances where magnetic fields exist, but not as a result of a permanent magnet. 1. Electric current causes a magnetic field. Thus, any wire carrying a current or even a current without a wire (like a lightning bolt) will be surrounded by a magnetic field. Since electric current is made up of moving electric charges, it is actually true than any moving electric charge creates a magnetic field. 2. It is difficult to observe outside of a scientific laboratory, but when there is an electric field that is varying in time, that creates a magnetic field. Though not easy to demonstrate directly, this turns out the physical phenomena the allows the creation of elecrtromagnetic waves, e.g. like the light we see with our eyes. 3. Thirdly, one can cause materials that are not able to work as permanent magnets to act as temporary magnets. This is the basis for electromagnets. A steel or iron core with an electric current running through a coil surrounding the core will produce a magnetic field. If you simply cut off the power source, the electric current will no longer flow through the coil. No electric current, no magnetic field. When a non-permanent magnet is created, the magnetic field it produces is just the same as the magnetic field of a permanent magnet, until the source is removed and the field disappears. All of these matters together are an essential part of the basics of electromagnetism which describes how and why the phenomena work.
