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.
You turn an electric dipole end for end in a uniform electric field.How does the work you do depend on the initial orientation of the dipole with respect to the field?
The work done by you to turn the electric dipole end for end in a uniform electric field depends on the initial orientation of the dipole with respect to the field. If the dipole is initially oriented such that its positive and negative charges are parallel to the electric field, then no net work is done as the electric field does not do any work on the dipole as the electric field lines do not transfer any energy. On the other hand, if the dipole is initially oriented such that its positive and negative charges are perpendicular to the electric field, then work is done by you to turn the dipole as the electric field exerts a force on the charges in the dipole in opposite directions, causing them to move in opposite directions. As a result, you have to do work to move the charges and turn the dipole.
Electric dipole in uniform magnetic field?
An electric dipole consists of two equal and opposite charges separated by a distance. When placed in a uniform magnetic field, the charges experience a force in opposite directions due to their opposite velocities in the field. This results in a torque acting to align the dipole along the field lines of the magnetic field.
Why earth magnetic field is a dipole?
The Earth's magnetic field is primarily a dipole because it is generated by the movement of molten iron in the outer core. This movement creates electric currents, which in turn generate a magnetic field with north and south poles similar to a bar magnet. This dipole nature of the Earth's magnetic field helps protect the planet from solar wind and cosmic radiation.
The orientation of a rock’s magnetic field can tell you its?
The orientation of a rock's magnetic field can tell you the direction in which the rock was formed, as the magnetic minerals in the rock align themselves with the Earth's magnetic field at the time of formation. It can provide insights into the geological history of the rock, including its age and past movements.
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.
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.
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.

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 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.

Why force exerted by a magnetic field on stationary elctric dipole is zero?
The force exerted by a magnetic field on a stationary electric dipole is zero because a magnetic field only exerts a force on moving charges. Since the electric dipole is stationary, there is no motion of charges for the magnetic field to act upon, hence no force is experienced.
How does the magnetic orientation of lava layers demonstrate reversals of earths magnetic field?
When lava cools and solidifies, magnetic minerals within it align themselves with Earth's magnetic field. By studying the orientation of these minerals in lava layers, scientists can track changes in the Earth's magnetic field over time. Reversals of the Earth's magnetic field are reflected in lava layers as bands of alternating magnetic orientation.
An electric dipole is placed in a nonuniform electric filedIs there a net force on the dipole?
Yes, there will be a net force on the electric dipole in a nonuniform electric field. The force will cause a torque on the dipole, leading to its orientation changing in the direction of the field.
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.
