dipole when placed in nonuniform electric field it experiences a net force if field is varying in direction but if field is nonuniform in magnitude then force depends on its posititon it may experience a torque again depends on depends on its posititon so it may translate as well as rotate

When an electric field is applied to a metallic crystal the movement of electrons is?
When an electric field is applied to a metallic crystal, the movement of electrons is towards the direction opposite to the field. This is because electrons are negatively charged particles and will experience a force in the opposite direction to the electric field. This movement of electrons constitutes an electric current.
What happens to a positively charged object place within a positive electric field?
It will be pushed away from the source of the electric field.
What happens to electric potential when the electric field is increased?
When the electric field is increased, the electric potential also increases. This is because electric potential is directly proportional to the electric field strength. In other words, as the electric field becomes stronger, the potential energy per unit charge also increases.
How field effect operates in organic chemistry?
In organic chemistry, the field effect refers to the influence of an electric field on the reactivity of a molecule. This effect can alter the distribution of electron density within a molecule, leading to changes in bond strength, nucleophilicity, and acidity. Field effects play a critical role in reactions involving charged species or polar molecules.
How do polar molecules align themselves in a field?
Polar molecules align themselves in a field because they have a positive and negative end. When placed in an electric field, the positive end of the molecule will align towards the negative side of the field, while the negative end will align towards the positive side. This alignment helps to minimize the energy of the system.
What is the significance of electric dipole in a polar molecule when an external electric field is applied?
in magnetic relays
What is the induced current in the loop when a magnetic field is applied?
When a magnetic field is applied to a loop, it induces an electric current in the loop.
When an electric field is applied to a metallic crystal the movement of electrons is?
When an electric field is applied to a metallic crystal, the movement of electrons is towards the direction opposite to the field. This is because electrons are negatively charged particles and will experience a force in the opposite direction to the electric field. This movement of electrons constitutes an electric current.
What is a arc?
discharge: electrical conduction through a gas in an applied electric field
What happens to a positively charged object place within a positive electric field?
It will be pushed away from the source of the electric field.
How does a torque affect the dipole in an electric field?
A torque applied to a dipole in an electric field causes the dipole to align itself with the direction of the field. The torque will tend to rotate the dipole until it reaches the stable equilibrium position where it is aligned with the electric field.
What happens to the strength of an electrical field as you get closer to it?
The strength of an electric field increases as you get closer to it. This is because the electric field lines are more concentrated closer to the source of the field. The strength of an electric field is inversely proportional to the square of the distance from the source.
What controls the flow of current with an electric field?
The flow of current in a material is controlled by its conductivity, which is influenced by the presence of an electric field. When an electric field is applied, it can cause charged particles in the material to move, resulting in the flow of current. The conductivity of the material determines how easily current can flow in response to the electric field.
What happens when an electric field is placed inside a magnetic field?
Electricity is formed (electrons move )
What is the electric field between two plates given a specific voltage?
The electric field between two plates is determined by the voltage applied across them. The electric field strength is directly proportional to the voltage and inversely proportional to the distance between the plates.
What is the effect of electric field on dielectric material?
An electric field applied to a dielectric material causes the material's dipoles to align with the field, inducing polarization. This polarization reduces the overall electric field inside the material, making it an insulator. This effect increases the capacitance of capacitors and reduces the field strength in electrical systems.
What happens to the magnitude of a magnetic field if the electric field that induces it increases the rate at which it changes?
The magnitude of the magnetic field is decreased
