Transformer turns ratio
Yes, the two things that chage the number of flux lines in a transformer(electromagnet) are the number of turns in the windings and the amount of current flow
You can use multiple appliances as long as long as you don't draw more current than the transformer can supply.
AC current or DC current can be used in transformers. A transformer is made of two coils of wire, the input coil induces a current into the output coil. Transformers change the voltage either up (step up transformer) or down (step down transformer). The amount of change in voltage is dependent solely on the number of windings in both coils in the transformer. DC transformers work exactly the same way AC transformers do.
If the number of turns in the primary is the same as the secondary, this would be an isolation transformer. Primary and secondary voltages should match (minus the inherent transformer losses), as should the current.
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
RATIO ERROR The secondary current is less than the expected value. The secondary is less in magnitude. This diffence is known as ratio error. PHASE ERROR The angle between the expected and actual secondary current is known as phase error.

If I am not wrong then you have asked about a transformer. And its a current transformer. By theory of voltage transformer we know that Vs/Vp = Ns/Np So for answering your question we need the value of number of turns in primary and secondary coil. But you can use this equation to find your answer if you have other values. By using ohmic law you can convert voltage to current.
This is what is known as a 1:1, or ISOLATION Transformer. There is no change to the Voltage or Current of the input, but this does provide a separation between the input and output of the transformer. This separation is sometimes required for safety purposes, especially in a medical environment.
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.
Actually current transfomer is step up voltage transformer n step down current transformer as current transfomer is having single primary turn of thick conductor but having more number of secondary turn of thin wires..so wkt tansformer ratio k= n2/n1=v2/v1=i1/i2. so it steps up volatge n steps down current...so we use current transformer as a step up transformer almost in all generating stations. Current transformers typically have terminals for a voltmeter on their case and a hole through that case. If you run your current carrying lead through the hole and connect an appropriate voltmeter (the voltmeter's design and resistance may affect the results) to the voltage terminals, the voltmeter will indicate the current in the lead times some factor which should be marked on the current transformer. If you thread the current lead through the hole N times then the voltmeter will indicate N times what it would read with the lead going through once (assuming that the ampere turns resulting do not cause saturation of the transformer's core.
The turns ratio of a transformer is the number of primary turns to secondary turns. This defines how the transformer will change the voltage and current. For N1 primary turns, and N2 secondary turns, N1/N2 will be the turns ratio; the secondary voltage will be:the primary voltage x (N2/N1); The secondary current will be:primary current x (N1/N2)
