The direction of an induced voltage is such that it always acts to oppose any change of current which causes it.So, for example, during the first quarter-cycle of a sine wave, when the current is increasing, the induced voltage acts oppose that change (increase) -in other words, it acts in the opposite direction to that current. During the second quarter-cycle of a sine wave, when the current is decreasing, the induced voltage again acts opposethat decrease that change (decrease) -in other words, it acts in the same direction to that current -trying to sustain that current.
the direction of the rotation of dc shunt generator could be changed only by changing the direction of rotation of the prime mover
"Induced" is the verb you are looking for. A current is induced in the secondary circuit by the current in the first changing, provided both conductors are close enough for the driving current's electro-magnetic field to enclose the second conductor. Note that word "changing". Direct current produces a field but that remains constant and does not induce a secondary current, as a.c. does.
Sampling is needed in order to determine the properties of a distribution or a population. Sampling allows the scientist to determine the variance in an estimate.
Molecular
It (1) provides a means of connecting a rotating coil to the external circuit, and (2) it is a rotating switch which ensures that the direction of the current through the coil always acts in the same direction relative to the magnetic field in order to ensure its torque acts in the same direction.
Paleomagnetism is the study of rock magnetism in order to determine the intensity and direction of Earth's magnetic field in the past.
you determine the answer of this by figuring out when this is true. Is it true when N equals 4? when n equals 0? You should be able to find the number when it changes from true to not true, and you should be able to determine in which direction it will continue to be true. you should end with n is less than or equal to a number in order for this statement to be true.
Induced vomiting
The issuing bank is always printed on the money order. There should be no problem determining where it originated.

Determine the tone

first of all the voltage doesn't change what changes is the current direction the way they do it is by using magnet . electrons tend to escape from the magnetic field . you can find on you tube how a motor works for better idea.
Ramadam is a month of pray and fasting. Since practicing Muslims are required to face Mecca in order to pray, it becomes a question of determining which direction to face. With out a GPS device, it would require knowledge of constellations and time of year in order for a Muslim to determine which direction is Mecca.
Scientists use a test cross to determine if an organism is heterozygous or homozygous dominant.
Traditionally, a tiki face should be placed facing outwards, towards the open in order to act as a protective guardian.
A fan motor rotates in the direction dictated by the type of blade it is using to move air in the desired direction. Both CW and CCW blades are used to do the same thing(move air in a particular direction). It simply depends on which type of blade one has in order to accomplish this and whichever blade you have will determine the direction of rotation of the motor driving it.
