Faraday\'s law does not depend on the number of times the coil turns.
Answer Selected Answer: False
Your 11 kv to 220 volts represents a 50 to 1 stepdown. (There is 50 times more voltage in the primary than in the secondary.) You'll have to have a 50 to 1 turns ratio. That means 1/50 of the number of turns in the primary will be in the secondary, and that is 64 turns.
If the number of turns in the primary side of the transformer is 200 and the number of turns in the secondary coil is 100, the turns ratio is 200 to 100, or 2 to 1. This application would be a step-down transformer, reducing voltage by one half and doubling current.
The inductance of a coil is directly proportional to the square of the number of turns (N) in the coil. This means that if the number of turns increases, the inductance also increases, assuming other factors such as core material and coil dimensions remain constant. Specifically, the relationship can be expressed by the formula ( L \propto N^2 ), where ( L ) is the inductance. Therefore, doubling the number of turns will quadruple the inductance.
ratio of secondry voltage to primary voltage is called voltage transformation ratio
The voltage ratio is the same as the turns ratio for an ideal transformer, and most transformers are close to being ideal. So use the following equation:Vs/Vp = Ns/Np

Transformer turns ratio
ratio
It depends on the ratio of the number of teeth on the two gears.
Your 11 kv to 220 volts represents a 50 to 1 stepdown. (There is 50 times more voltage in the primary than in the secondary.) You'll have to have a 50 to 1 turns ratio. That means 1/50 of the number of turns in the primary will be in the secondary, and that is 64 turns.
That number is simply labeled with the unit "ampere-turns".
"The magnetic field produced by each turn interacts with the field of other turns and multiplies the effect, causing the inductance of a coil of wire to increase by the number of turns (N) squared. Therefore, if you double the number or turns, you quadruple the inductance."
The strength of an electromagnet is directly proportional to the number of turns in the coil. Increasing the number of turns in the coil increases the magnetic field strength produced by the electromagnet.
The turns ratio is the number of primary turns divided by the number of secondary turns. This is the same ratio as input current to output current. ie the turns ratio N = I1/I2
Transformer ratio, more correctly turns ratio, is the number of turns in the primary winding divided by the number of turns in the secondary winding.
The strength of an electromagnet depends on the current flowing through the coil, the number of turns in the coil, and the magnetic properties of the core material inside the coil. Increasing the current or number of turns will strengthen the electromagnet, while using a high-permeability core material can also enhance its magnetic strength.
You make a mark on the tire and rotate the tire one full round while counting the number of turns of the drive shaft. If the shaft turns 3 times while the tire turns once the ratio is 3:1.
