Electrons revolve around the nucleus. A revolving electron is equivalent to a current loop. Hence, it produces a magnetic moment.

Which force field can accelerate an electron but never change its speed?
I would say a magnetic field. When an electron enters a magnetic field that is oriented perpendicular to its path of travel it causes the electron to loop in a circle. While the speed stays the same the velocity is constantly changing due to the circular motion. Hence same speed but undergoing an acceleration.
What makes a magnet magnetic?
How Magnets WorkAlignment of the outer valence electron orbitals in iron. Every atom in iron has a north side and a south side. If they are all aligned, the entire piece of metal will have a north side and a south side, and it is therefore magnetic. The outer orbitals have only one electron and their motion in the circular path gives rise to a central force through the center of the orbital whose direction is based to the right hand curve rule. And its this force that either expels or attracts a magnet towards other iron materials. Note: polarity of magnetic dipoles is described as north and south. polarity of electric dipoles is +/-.
What is the Force that pushes or pulls magnetic material near a magnet?
Magnetic forces are produced by the motion of charged particles such as electrons. Magnetism is one of the fundamental forces of nature.
Plate motion is caused partly by magnetic reversals convection currents continental drift or volacnic hot spots?
Convection currents
What do forces produce?
forces produce motion, magnetism, acceleration, climate change, and movement
How magnetic moment of electron is associated with angular momentum of electron?
magnetic moment of a particle is due to its motion around some other orbits or about its own orbit i.e due to its orbital angular momentum or its spin angular momentum.
What two kinds of electron motion are important in determining the magnetic property of a material?
Orbital and spin motion of electron
What are Magnetic Properties of Metals?
Iron (Fe) Cobalt (Co) and Nickel (Ni) iron, steel, nickel, and cobalt all have magnetic properties. Lodestone is also magnetic and was used to make early compasses a long time ago because it has magnetic metal elements in it.
How is magnetic field produced in an atom?
Simple Answer:An isolated atom has three sources for a magnetic field, the electron motion, the electrons' intrinsic magnetic moment and the nuclear magnetic moment.Explanation:First, the electrons around the atom are in motion and if there is a net circulating flow (i.e. a nonzero angular momentum) then the motion of the electrons is a current that produces a magnetic field in basically the same process that any current produces a magnetic field.Second, the electron itself has a magnetic property as a particle called the magnetic moment. The magnetic moment of the particle effectively makes it a tiny permanent magnet. (Other elementary particles have this property also.) The electrons in an atom can be arranged so that the magnetic fields of the individual electrons' magnetic moments add together or cancel each other out. If they do not totally cancel each other out, the atom as a whole then has the property of a tiny magnet. If arranged in a bulk form, like an iron magnet, these electrons can be the primary source of the permanent magnetic field of a material.Third, the nucleus of an atom is also made up of particles with an intrinsic magnetic moment, just as the electron is. In particular, the protons have a large magnetic contribution. It is not often the case that the nuclei of atoms spontaneously align with the nuclei of other atoms to produce a net permanent magnetization of a material, but it is a technologically important characteristic, e.g. for magnetic resonance imaging (MRI).

How is a magnetic field produced in an atom?
This depends if they are charged or neutral and if they are moving or not. A: If they are not moving then nothing usually and if they are neutral nothing. B: If they are charged and moving then they begin to accelerate in the direction of the magnetic field. C: If the object is a magnetic object for instance Iron that shares its electrons metallically then it will feel a acceleration in the direction of the magnetic field all other object will feel nothing.
What is helical motion?
Helical motion refers to the motion of an object moving along a helix, which is a three-dimensional spiral shape. This type of motion combines linear and rotational movements, resulting in a path that moves both along an axis and in a circular pattern simultaneously. Helical motion is commonly observed in various mechanical systems and natural phenomena.
Distinguish an electric from a magnetic field?
An electric field can created by a presence of a charge particle such as electron or proton. While a magnetic fieldis created due the relative motion of a charge particle with repeat to a stationary observer, motion of the charge particle.
Why are some material magnetic and some are not?
Almost all magnetism is caused by electrons.Individual electrons have an intrinsic magnetic moment.In an atom, the electron's angular motion around the nucleus also causes a magnetic moment.Since all solid materials are composed of atoms and include electrons, the question becomes: why aren't all materials magnetic?Many atoms only have paired electrons, with the intrinsic magnetic moment of each electron cancelled out by the intrinsic magnetic moment of its paired electron.Many atoms only have "filled sub-shells", which have zero net angular motion.Atoms with either unpaired electrons, or unfilled sub-shells, or both, are inherently magnetic. However, in many materials, the magnetic moments of these atoms point in random directions, so they cancel out and the bulk material is nonmagnetic.It is to do with the pairing of electrons and their dipoles. Basically metals with uneven electrons or half shells are magnetic. Three main metals that are Iron, Cobolt and Nickel. With Iron being the main one.Hope this helps! =]
What affects the size of the magnetic moment of a diatomic molecule?
Without the full quantum mechanical treatment let's look at an atom. In all atoms, the electrons are in motion, and are creating magnetic fields around their paths of travel. And each electron is in a specific orbital (Fermi energy level) and will have an associated angular momentum unique to that specific orbital. To discover the atomic (magnetic) dipole moment, we have to gather up and add the spins of each of the electrons, and also find and sum each orbital angular momentum where an electron is operating. With the spins of the electrons and the angular momenta of the orbitals, we can then combine those to discover the total angular momentum. From there, it's a hop, skip and a jump to find the magnitude of the atom's dipole moment. In a molecule, we have to do this for multiple atoms. Additionally we have to make accommodations for the magnetic moments of any unpaired electrons. We must also account for nuclear spin configuration and the energy state of the molecule to arrive at the magnitude of the magnetic moment. We might have to consider nuclear magnetism in the isotopes of some elements, but these are the basic variables that must be managed to find the magnitude of the magnetic moment of a molecule. A link can be found below to check facts and review the mathematics involved.
What is magnetic domain?
A magnetic domain is an atom or group of atoms within a material that have some kind of "net" or uniform electron motion. Let's look a bit more closely to see what that means and what the implications are. A fundamental property of any charged particle is that when it is in motion, it creates a magnetic field around its path of travel. Electrons are negatively charged particles, and they create electromagnetic fields about themselves as they move. We know that electrons orbit atomic nuclei, and they create magnetic fields while doing so. Let's keep going from there. If we take one or more atoms or groups of atoms and align them so that they have some kind of uniform electron motion, an overall magnetic field will be present in this region of the material. The individual magnetic fields of some electrons will be added together. The uniform motion of the electrons about atoms in this area creates a magnetic domain. In "regular" iron, these magnetic domains are randomly arranged. But if we align a large enough group of these magnetic domains, we'll have created a magnet.
Which force field can accelerate an electron but never change its speed?
I would say a magnetic field. When an electron enters a magnetic field that is oriented perpendicular to its path of travel it causes the electron to loop in a circle. While the speed stays the same the velocity is constantly changing due to the circular motion. Hence same speed but undergoing an acceleration.
