The force on a charge by a magnetic field is given by F = Bq v sin@
v - the speed of the charged particle with charge q. B - magnetic field induction in tesla. @ is the angle between the velocity vector and magnetic field vector.
As dipole is stationary, the speed of charges is zero. So the force = 0
Hence the result.

Magnetic induction due to a short dipole?
Coulomb's law applies exactly only when the charged bodies are much smaller than the distance separating them and therefore can be treated approximately as point charge B = F /M M = 1 B = F
From where earth's dipole field originates?
Earth's dipole magnetic field is thought to originate from the movement of molten iron in its outer core. This movement creates electric currents that generate a magnetic field through a process called geodynamo. The magnetic field then extends from the core to the space around Earth, forming a protective shield known as the magnetosphere.
What has occurred when rocks formed millions of years ago show the location of the magnetic poles at the time of their formation?
When rocks formed millions of years ago show the location of the magnetic poles at the time of their formation, it indicates the phenomenon of geomagnetic reversal, where the Earth's magnetic field has flipped its polarity over time. This provides valuable information for studying the history of Earth's magnetic field and the movement of tectonic plates.
Does hemoglobin attracted by external magnetic field?
Hemoglobin is not attracted by an external magnetic field because it is a diamagnetic substance which means it weakly repels magnetic fields. This property is due to the lack of unpaired electrons in its structure, making it largely unaffected by magnetic forces.
What is the difference between instantaneous dipole and induced dipole?
Dipole-dipole is between two polar molecules, that would be polar anyway. Dipole-induced dipole is between a polar molecule and a non-polar molecule that is now polar due to the proximity of a polar molecule.
What is the formula for calculating the magnetic field due to a dipole?
The formula for calculating the magnetic field due to a dipole is given by: B dfracmu04pi left( dfrac2mr3 right) where: ( B ) is the magnetic field, ( mu0 ) is the permeability of free space, ( m ) is the magnetic moment of the dipole, and ( r ) is the distance from the dipole.
What is difference between between electric dipole moment and magnetic dipole moment?
An electric dipole moment is a measure of the separation of positive and negative charges in a system, creating an electric field. A magnetic dipole moment, on the other hand, is a measure of the strength and orientation of a magnetic field created by a current loop or a moving charge. In essence, electric dipole moments deal with electric fields generated by charges, while magnetic dipole moments pertain to magnetic fields generated by moving charges.
How do you calculate dipole field?
The magnetic field created by a dipole can be calculated using the formula: B = (μ0 / 4π) * (2m / r^3), where B is the magnetic field strength, μ0 is the permeability of free space, m is the magnetic moment of the dipole, and r is the distance from the dipole.
What should be orientation of dipole in magnetic field?
The orientation of a dipole in a magnetic field will align along the direction of the magnetic field. The north pole of the dipole will point towards the south pole of the magnetic field and vice versa, in order to minimize the potential energy of the system.
Why magnetic length is taken as 2L?
The magnetic length is defined as 2L because it represents the effective length of a magnetic dipole, where L is the distance from the center of the dipole to each pole. This doubling accounts for both poles of the dipole, as the magnetic field generated is influenced by the entire length of the dipole, not just one end. Hence, the factor of 2 ensures that the full extent of the dipole's influence is considered in calculations and analyses of magnetic fields.
If a magnetic dipole is placed in a magnetic field the dipole is found to have both rotational and translational motion.what would you infer about the magnetic field?
If a magnetic dipole placed in a magnetic field exhibits both rotational and translational motion, it suggests that the magnetic field is not uniform. A non-uniform magnetic field will exert torque on the magnetic dipole, causing it to rotate, and may also impart a force causing translational motion. These observations can help characterize the spatial variation of the magnetic field.
What is the relationship between an electron's spin angular momentum and its spin magnetic dipole moment?
The relationship between an electron's spin angular momentum and its spin magnetic dipole moment is that the spin magnetic dipole moment is directly proportional to the spin angular momentum. This means that as the spin angular momentum of an electron increases, so does its spin magnetic dipole moment.
What is the potential energy of a point magnetic dipole of moment M placed in a uniform magnetic field B?
The potential energy of a magnetic dipole in a magnetic field is given by U = -M · B, where M is the magnetic moment and B is the magnetic field. The negative sign indicates that the potential energy decreases as the dipole aligns with the field.
What is the relationship between magnetic dipole energy and the behavior of magnetic materials?
The magnetic dipole energy is a measure of the strength of the magnetic field in a material. It is related to the behavior of magnetic materials because it influences how the material responds to external magnetic fields. Materials with higher magnetic dipole energy tend to exhibit stronger magnetic properties and are more likely to align their magnetic dipoles in a specific direction. This alignment affects the overall magnetic behavior of the material, such as its magnetic susceptibility and coercivity.
What are the types of dipole?
The two main types of dipoles are electric dipoles, which consist of two opposite charges separated by a distance, and magnetic dipoles, which involve a pair of magnetic poles with opposite polarities. Electric dipoles are commonly found in molecules, while magnetic dipoles are seen in magnets and certain atomic particles.
Physical significance of magnetic dipole moment?
The magnetic dipole moment represents the strength and orientation of a magnetic field produced by a current loop or a magnet. It is a measure of the ability of an object to interact with an external magnetic field. This property is fundamental in understanding the behavior of magnetic materials and the interactions between magnetic objects.
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.
