All Transformers are magnetic. A transformer is two (or more) coils of wire wound together. The varying magnetic field created by the primary winding induces a current in the secondary coils proportional to the ratio of the number of turns. You're probably refering to a switchmode powersupply as a "electronic transformer" (which is bad nomenclature, by the way). A switch mode supply actually contains a normal transformer in its core, along with circuitry to allow for a wide input fange and a narrow output range.
An electronic stopwatch gives a higher accuracy than a mechanical stop watch.
An isolation transformer is usually a ferromagnetic transformer. The question needs to be framed more usefully.
The difference between current transformer and potential transformer is that the secondary of a current transformer can not be open circuited while under service whereas that of the potential transformer an be open circuited without any damage to the transformer.
The difference between an electronic organ and an electronic piano is in the sounds produced. Sometimes, on the higher end models, the electronic piano will have a piano touch, weighted keyboard.
Variable transformer may also refer as auto transformer. We can vary the output voltage of the transformer. But in the ordinary transformers output voltage is already designed.
The difference is between how the windings relate to magnetic material around which they are wound. If this magnetic material surrounds the windings then the device is said to be a shell type transformer. If the windings cover the exterior of the magnetic material then the transformer is said to be of the core type. Please see the link.
there is nothing like a balanced and unbalanced transformer.
What is the difference between an ordinary transformer and resonant coupling energy transfer?
Both are same. This is an instrument transformer used for metering & protections.
The 3 kVA transformer will weigh double the 1.5 kVA transformer.

No difference - a cassette contains magnetic tape.

potential transformer is to maser and protection purpose the ivt is used for synchronicing purpose
