the positive end of one molecule attracts the mobile electrons of the nearby non polar molecule in this way polarity is induced these forces called as dipole-induce dipole forces
What else can I help you with?
Why is alternating voltage induced in the rotating armature of a generator?
The windings of the armature are constantly cutting magnetic lines of force of opposite polarities
When lines of force are cut by a conductor you have magnetic?
Presumably, you are asking what happens when a conductor 'cuts' lines of magnetic flux? If so, then a voltage is induced across the ends of that conductor.
How does the process of electromagnetic induction work?
The process by which a substance, such as iron or steel, becomes magnetized by a magnetic field. The induced magnetism is produced by the force of the field radiating from the poles of a magnet.
Difference between statically and dynamically induced emf?
STATICALLY INDUCED EMFThe emf induced in a coil due to change of flux linked with it (change of flux is by the increase or decrease in current) is called statically induced emf.Transformer is an example of statically induced emf. Here the windings are stationary,magnetic field is moving around the conductor and produces the emf.DYNAMICALLY INDUCED EMFThe emf induced in a coil due to relative motion of the conductor and the magnetic field is called dynamically induced emf.example:dc generator works on the principle of dynamically induced emf in the conductors which are housed in a revolving armature lying within magnetic field
Which law gives the direction of induced current?
LENZ LAW gives the direction of induced current.
What is the induced electromotive force (EMF) in this loop?
The induced electromotive force (EMF) in a loop is the voltage generated when there is a change in magnetic field within the loop.
What is the induced emf in case (a)?
In case (a), the induced emf is the electromotive force generated in a coil or conductor due to a changing magnetic field.
When lines of force are cut by a conductor you have?
When lines of force are cut by a conductor, an electromotive force (EMF) is induced in the conductor according to Faraday's law of electromagnetic induction. This induced EMF can drive an electric current to flow in the conductor, resulting in the generation of electrical power.
Is induced voltage and induced currrent the same?
Induced voltage is alsocalled ghost or phantom voltage as if you apply a load it vanishes. induced voltage will be potential/electrical pressure. Amperage is the actual flow of current being used, Watts being its calibration of total power used.
What is the average induced emf in the loop?
The average induced electromotive force (emf) in the loop is the average amount of voltage generated in the loop due to a changing magnetic field.
When lines of force are cut by what you have electromagnetic induction?
When magnetic flux lines of force are cut by induced voltage between magnetic and electric currents. Electromagnetic induction is created.
How many types of van der Waals forces exist?
These forces are: dipole-dipole force, hydrogen bond, induced dipole force and London dispersion force.
What happens when a loop of wire cuts magnetic line of force?
When a loop of wire cuts magnetic lines of force, an electromotive force (EMF) is induced in the wire. This phenomenon is known as electromagnetic induction, and it is the basic principle behind generating electricity in generators and the functioning of electric motors. The induced current in the loop is proportional to the rate at which the magnetic lines of force are cut by the loop.
Difference between back EMF and induced EMF?
An induced electromotive force (emf) is an induced voltage. Voltage (emf) causes current flow, and this induced voltage will cause a current that is called the induced current.We might also add that the induced current will cause a magnetic field to expand about the current path, and this field will "sweep" the conductor. The sweeping of the conductor by that expanding magnetic field will set up an emf that will oppose the emf that was creating it.CommentTechnically, there is no such thing as an 'induced current'. It is voltage that is induced. Any current flows as a result of that induced voltage being applied to a load. But that current is certainly NOT induced!
What does the torque do to the rotor?
It rotates the rotor. Torque is produced by the magnetic force on the current induced in the squirrel cage. This magnetic force acts as torque on the rotor as a tangential force that makes it spin.
What is the direction of the force experienced by the current carrying wire due to itself induced magnetic field?
north
How is an electormotive force induced in a coil?
An electromotive force (emf) is induced in a coil when there is a change in magnetic flux passing through the coil. This change in magnetic flux can be caused by either moving a magnet near the coil or by changing the current flowing through a nearby coil. According to Faraday's Law of electromagnetic induction, the emf induced in the coil is proportional to the rate of change of magnetic flux.
