Which is a characteristic of a step–down transformer?

Answer:  

Step Down Transformer: The Transformer that expands the voltage from Primary (essential) to Secondary (auxiliary) (more optional twisting turns than essential winding turns) loops called Step Down Transformer.

Explanation:

A transformer that reduces high voltage to low voltage is called a step-down transformer. The step-down transformers are that transformers which have high turns on its primary coils than secondary.  

Where  

Vp = Voltage in Primary Coil  

Ip = Current in Primary Coil  

Vs = Voltage in Secondary Coil  

Is = Current in Secondary Coil

mistakes are ok

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!
