Well Transformers are used to either raise the voltage (step-up) or lower the voltage (step-down). Transformers have a high voltage winding (HV) and Low voltage winding (LV). If being used as step down then the supply will be connected to the winding with more turns and load will be connected to winding with fewer turns. This is reffered to as the turns ratio N1/N2 .If the ratio is 1/1 and 120V applied then the secondary voltage is 120v. If N1/N2 is 2/1 then there are twice and many primary turns as secondary turns and if 120 V applied to primary there would be 60 V on secondary.

Difference of step up and step down in terms of no of loops in the secondary coil?
If the primary coil has ten loops and the secondary coil has five loops then the secondary coil works as a 50% step down
What is difference between solenoid and coil?
Solenoid has a longer length compared to its diameter. The Distance between two loops in a solenoid is longer. while Coil has the bigger diameter. The distance between two loops in a coil is shorter compared to its diameter.
What is the voltage in the secondary coil if the primary coil is supplied with 120V?
I assume that you are speaking theoretically, as it is unlikely that a practical transformer will have just ten turns ('loops') in its secondary coil. In any event, you have not provided sufficient information to be able to answer your question, as it's necessary to know how many turns there are on the primary winding.
What is the current in the secondary coil fi the current in the primary coil is 5.0A 10 loops on primary coil and 20 on secondary coil?
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.
A step-down transformer has 525 turns in its secondary and 12500 turns in its primary If the potential difference across the primary is 3510 V what is the potential difference across the secondary?
The potential difference across the secondary coil will be 147.42 Volts
What is a long coil of wire with many loops?
armature
Why the magnetic field strength of an electromagnet be reduced in decrease the number of loops in the coil?
Each coil contributes to the magnetic field, and the contributions of the individual loops all add up.
What is a current-carrying coil of wires with many loops?
solenoid
What is the difference between current coil and voltage coil?
These terms apply to the coils inside a wattmeter. 'Pressure coil' is an archaic term for 'voltage coil', which is connected in parallel with the supply, while the 'current coil' is connected in series with the load.
What is a long coil of wire with many loops called?
a long wire with many coils is called a coil
What are many loops of wire placed one on top of the other?
Coil :)
Many loops of wires on top of one and another?
Is called a coil.
