In a uniform field, dipole motion aligns with the field, causing the dipole to rotate until it is parallel to the field.
The torque experienced by a dipole in a uniform field is equal to the product of the magnitude of the dipole moment and the strength of the field, multiplied by the sine of the angle between the dipole moment and the field 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.
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.
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.
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)
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.

in the same direction as the field
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.
when angle 0 b/w dipole moment vector p and electric field vector E is zero then potential energy of dipole, U=-pEcos0 =-pE and torque=pEsin0=0;which means that the electric dipole is in stable equilibrium.
