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!
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.
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.
The magnetic flux passing the coil changes by its rotation thus induced emf is produced and induced current flows
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.
To produce lift with the least amount of induced drag.
The production of lift creates induced drag. To create more lift, more airspeed is needed, and with airspeed, comes drag.
Induced drag is the name given to the force of drag 'induced' by the act of increasing lift. Induced drag is directly related to how much lift the wing is producing, and usually angle of attack induced drag is usually caused by flow separations at high angles of attack and wing tip vortices, which is the main form of induced drag. Delta wings have massive induced drag because of their high chord which presents a high frontal area at high angles and leading edge vortices used to produce lift at low speed which generate lots of drag. At high speed and low angle however, the leading edge vortex no longer occurs and the wing has a very low frontal area which decreases the induced drag to almost nothing. Unlike other forms of drag, induced drag actually decreases with higher speed.
For no lift, The induced drag will be zero. However, there will still be drag due to viscous forces and pressure forces.
To counter the rotation induced by the lift rotor(s)
induced spawning is an artificial breeding of fishes same as induced breeding.
yes increasing wingspan does increase glide distance.. the reasons are complicated but it has to do with increasing lift while simultaneously decreasing induced drag
In aerodynamics, lift-induced drag, induced drag, vortex drag, or sometimes drag due to lift, is a drag force that occurs whenever a moving object redirects the airflow coming at it. This drag force occurs in airplanes due to wings or a lifting body redirecting air to cause lift and also in cars with airfoil wings that redirect air to cause a downforce. With other parameters remaining the same, induced drag increases as the angle of attack increases.Source of induced drag:Lift is produced by the changing direction of the flow around a wing. The change of direction results in a change of velocity (even if there is no speed change, just as seen in uniform circular motion), which is an acceleration. To change the direction of the flow therefore requires that a force be applied to the fluid; lift is simply the reaction force of the fluid acting on the wing.When producing lift, air below the wing is generally at a higher than atmospheric pressure, while air above the wing is generally at a lower than atmospheric pressure. On a wing of finite span, this pressure difference causes air to flow from the lower surface wing root, around the wingtip, towards the upper surface wing root. This spanwise flow of air combines with chordwise flowing air, causing a change in speed and direction, which twists the airflow and produces vortices along the wing trailing edge. The vortices created are unstable, and they quickly combine to produce wingtip vortices.[2] The resulting vortices change the speed and direction of the airflow behind the trailing edge, deflecting it downwards, and thus inducing downwash behind the wing.Wingtip vortices also modify the airflow around a wing, compared to a wing of infinite span, reducing the effectiveness of the wing to generate lift, thus requiring a higher angle of attack to compensate, and tilting the total aerodynamic force rearwards. The angular deflection is small and has little effect on the lift. However, there is an increase in the drag equal to the product of the lift force and the angle through which it is deflected. Since the deflection is itself a function of the lift, the additional drag is proportional to the square of the lift.The total aerodynamic force is usually thought of as two components, lift and drag. By definition, the component of force parallel to the oncoming flow is called drag; and the component perpendicular to the oncoming flow is called lift.At practical angles of attack the lift greatly exceeds the drag. Unlike parasitic drag on an object (which is proportional to the square of the airspeed), for a given lift, induced drag on an airfoil is inversely proportional to the square of the airspeed. In straight and level flight of an aircraft, lift varies only slowly because it is approximately equal to the weight of the aircraft. Consequently in straight and level flight, the induced drag is inversely proportional to the square of the airspeed. At the speed for minimum drag, induced drag is equal to parasitic drag.

Winglets descrease induced drag (drag from the production of lift) created by wing-tip vortices, simply turbulent airflow off the edge of the wing. So they do increase handling characteristics and fuel efficiency because of the increase in lift and decrease in drag. Hope this helped!
