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.
When an electric dipole is held in a non-uniform electric field, the dipole experiences a net torque causing it to align itself in the direction of the field. The dipole will tend to orient itself with its positive end facing towards the direction of the field and its negative end facing away from it. This alignment leads to a potential energy change in the dipole, with the dipole experiencing a force due to the non-uniform field.
The work done in rotating an electric dipole in a uniform electric field from parallel position to anti-parallel position is zero. This is because the torque applied to rotate the dipole is perpendicular to the direction of the electric field, so the work done is zero.
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.
In a uniform field, dipole motion aligns with the field, causing the dipole to rotate until it is parallel to the field.
An electric field parallel to an electric dipole will exert a torque on the dipole, causing it to align with the field. An electric field anti-parallel to an electric dipole will also exert a torque on the dipole, causing it to rotate and align with the field in the opposite direction.
When an electric dipole is held in a non-uniform electric field, the dipole experiences a net torque causing it to align itself in the direction of the field. The dipole will tend to orient itself with its positive end facing towards the direction of the field and its negative end facing away from it. This alignment leads to a potential energy change in the dipole, with the dipole experiencing a force due to the non-uniform 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.
It experiences a torque but no force. As the dipole is placed at an angle to the direction of a uniform electric field it experiences two opposite and equal forces which are not along the same line. This develops a torque which aligns the dipole along the field. The dipole does not experience any force as the two forces cancel each other.
yes, there is a NET field .electric dipole experiences a net field .(not in uniform E.Field)
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.
So interesting query! As we keep the dipole with its dipole moment along the direction of the electric field then it will be in stable equilibrium. IF we keep the same dipole inverted ie its dipole moment opposite to the external field then the dipole will be in unstable equilibrium.
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.
The work done in rotating an electric dipole in a uniform electric field from parallel position to anti-parallel position is zero. This is because the torque applied to rotate the dipole is perpendicular to the direction of the electric field, so the work done is zero.

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.
in the same direction as the field
In a uniform field, dipole motion aligns with the field, causing the dipole to rotate until it is parallel to the field.
