Why soft iron is placed in moving coil galvanometer?
1. to intensify the magnetic field by reducing the length of airgap across which the magnetic flux has to pass; 2. to give a radial magnetic flux of uniform density, thereby enabling the scale to be uniformly divided.
Why a current carrying wire has no magnetic dipole moment?
A current-carrying wire doesn't have a magnetic dipole moment because the magnetic field generated by the current flowing through the wire is a result of the collective motion of the moving charges, rather than individual aligned dipoles. The magnetic field produced by a current in a wire forms loops around the wire and does not exhibit a net alignment of magnetic poles to give it a magnetic dipole moment.
Give two examples of common force fields?
Gravitational field: The force field created by mass that attracts objects towards each other, such as the force that keeps planets in orbit around the sun. Magnetic field: The force field generated by moving electrical charges that attracts or repels magnetic materials, such as the force that aligns compass needles towards Earth's magnetic poles.
What process generates a current by moving an lctrical conductor through a magnetic field?
Magnetic induction. If you have conductor, then there are these free electrons bouncing back and forth between the atoms. They move in random directions and there is no unified movement which we could detect as electric current.From the Lorentz force of a charge moving through a magnetic field, we have the force as F = qv x B. Where v and B are vectors. The force will be perpendicular to both the velocity and the B field. Its magnitude is qvB*sin(Θ). So if your conductor is moving in a magnetic field, then those free electrons will experience a force accelerating them in a perpendicular direction.To give a sense of this, if the wire is laying flat on a paper running left and right, and the magnetic field lines are coming up out of the paper, if you move the wire in the up direction (on the page) then the electrons will be forced to move towards the right (along the conductor).
Under what circumstances can electrical charges produce a magnetic field?
Yes, a moving electric charge creates a magnetic field around its path of travel, and this is true for any charged particle. Further, it is the basis for the idea that the electromagnetic force is one force. Physics views electric fields and magnetic fields as being derived from just that one force we mentioned. When we see charges moving continuously, we will see a "standing" magnetic field around the current path. And the magnetic field can be made to do many useful things. This is the idea behind almost all electric power generation around the world as well as countless electronic applications.
What Magnetism .?
Basically, magnetism is the force that causes a nail or paper clip to be pulled toward a magnet. Play around with a magnet and you'll quickly see magnetism in action! Magnetism is the force generated by any moving charged particle or charged particles. A magnetic field is the result of the motion of a charged particle or charged particles, and this field is generated in no other way. Any time a charged particle moves, it creates a magnetic field around its path of travel. There are no exceptions that we know of. Magnetism is a term that speaks to the phenomenon associated with a magnetic field and with its action on other things. The creation of a magnetic field by a moving charge or moving charges is this fundamental concept that is behind the term electromagnetic force, which is one of the four fundamental forces in the universe. Electricity and magnetism are tied together inextricably because of this. This leads to other ideas directly associated with magnetism. Though any (every) moving charge generates a magnetic field, it is the movement of electrons that we most commonly consider. If enough electrons are moving in a uniform way in a group of atoms, it will give rise to an "external" magnetic field, and we call this a magnetic domain. It could be one atom or, as suggested, a group of them, but the key is the uniform motion of "enough" electrons to create the domain. This phenomena, that of magnetic domains, appears in ferromagnetic materials like iron. The domains are there. And if we perform some kind of operation to align a gross quantity of these domains, it will permit us to have a magnet. A permanent magnet is a piece of ferromagnetic material that has had its magnetic domains aligned under controlled conditions. The material is generally heated and exposed to a magnetic field. The field is held in place until the material is cooled so the magnetic domains are "locked in place" where they are. In an electromagnetic, we use electricity (moving electrons) to create a magnetic field. The wire for the electromagnet is wound around a ferromagnetic core, and when a direct current is run through the wire, the "uniform" motion of those electrons creates a magnetic field around each turn of the wire, and, because the windings are all "side by side" in the device, the fields are added to create the big external field. Any way you cut it, it takes a moving charge or moving charges to create a magnetic field, and magnetism is the phenomenon associated with the existence of a magnetic field or with the interaction of a magnetic field with other materials or even other magnetic fields.

Does the earth's magnetic field give information on the earth's interior composition?
The earth has electric currents in its structure, that create magnetic fields.
Can a charged particle moved through a magnetic field without experiencing any force?
No, a charged particle will experience a force when moving through a magnetic field as long as it has a non-zero velocity component perpendicular to the field. This force is known as the magnetic Lorentz force.
Ions Trapped in the Earth's magnetic field give rise to?
ultraviolet radiation
A loop of wire is placed in a uniform magnetic field.In which orientation of the loop is the magnetic flux linked with it maximum?
1. The orientation giving the maximum magnetic flux would be 90 degrees or perpendicular to the magnetic field because that gives the maximum amount of magnetic field lines able to pass through the area of the coil. The greater density of field lines gives a greater magnetic field. The orientation that would give a magnetic flux of zero is the plane of the coil to be parallel to the magnetic field, making no lines pass through the coil and thus no flux.
