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 is self induced?
When a current in a coil increases or decreases, there is a change in magnetic flux linking the coil,an e.m.f. is induced. This is called self induced e.m.f. and the process is called self induction.
What determines whether an induced current is a direct current or an alternating current?
There is no such thing as an 'induced current'. What is 'induced' is a voltage. The direction of the induced voltage is determined by the direction of the changing current that induces that voltage, because the induced voltage will always act to oppose that change in current. So, if the current is increasing, then the direction of the induced voltage will act to opposethe increase in current. If the current is decreasing, then the direction of the induced voltage will act to sustainthat current.
Why voltage induced when moving coil cuts flux?
The magnetic flux passing the coil changes by its rotation thus induced emf is produced and induced current flows
What is induction of electric current?
According to Farady's law, whenever the flux linking with the coil changes, emf will induce in that coil.Actually the material should oppose the flux changes, that opposition is the induced current. Induced current will set own flux, opposite to that of the flux changes.For further details, refer lenz law.
Are ferrets induced ovulators?
Jills are induced ovulators or ovulation is induced by mating. If mating does not occur, and the Jill (female ferret) remains in heat for long period of time, it can lead to serious illness.
How long does it take a cow to calve after being induced?
Generally, a few hours.
What is induced spawning?
induced spawning is an artificial breeding of fishes same as induced breeding.

Are the attractive forces between polyethylene chains due to permanent dipoles or induced dipoles?
The attractive forces between chains are due to instantaneous induced dipoles, London dispersion forces,( not induced diipoles due to permananent dipoles). Polyethylene chains are long and the number of electrons is large- the intermolecular attraction will be significant.
How do you you make a miscarriage happen?
For a induced miscarriage aka abortion you have to see a doctor and he will give you a surgical or medical abortion depending on your health and how far along you are.
Where are stars?
Long long ago, in a galaxy far far away.
What is spontaneous and induced mutations?
Mutations which are artifically induced with the help of mutagenic agents are called induced mutations
What does the word induced mean?
INDUCED has two meaningsSucceed in persuading or influencing (someone) to do something.Bring about or give rise to: "measures that induced a change"
