Because the electrical parts of a transformer do not move / rotate.
An earthing transformer provides a neutral in a delta connected system.
b'coz transformer is not a moving parts so it works on the princeple of mutual induction

Core Primary Winding Secondary Winding
In general, the lower the frequency of operation, the more weight must be added to the core laminations to avoid magnetic field saturation. This increases the size and weight of the transformer as the frequency decreases.
Skin effect is a physical effect that operates on thick conductors. In a transformer the conductors are usually too thin for any substantial skin effect to occur.
No a transformer toy is not suitable for a one year old child because there are many small parts that the child can accidentally put in his or her mouth.
Insulated primary and secondary windings and a silicon-steel core.
A generic 115vac/ 40 VA 24 volt transformer will work fine. Mars or Honeywell are the most common.
An output transformer can be bought at various stores online or off. Some of these include: Telco Depot, Parts Express, I Have IT and Tube lab among others stores.
Where ever you purchased the Transformer toys is a good start. Contact the store for more information. EBay is a great website when you can't find something particular.
