Can a voltage exist across an ideal inductor that has a steady DC current flowing through it

yes it can
5 (25%)
no it cannot
11 (55%)
I have no idea

I am in no way,shape,or form,going to bow down to your stupidity,and waste my time on something that should be common knowledge to you--as it is with everyone else here.
And to think,you thought you had the smarts to give EMJ a hard time on his understandings about inductors and coils--and me for that matter.

You are just a transparent faker and a bluffer Brad.  The simple truth is that you can't show anything to back up your claim at all.  So you are just doing the chicken chicken dance right now.

It's all FAKE on your part now Brad, everything you are saying is transparently FAKE.  The proverbial chicken on a hot plate doing a dance to stop his feet from burning.

QuoteYea--good one MH--only we do not have a loop,we have a coil attached to a voltage supply.

Brad

You are a bloody electronics rocket scientist Brad.

  if the CEMF was equal and opposite to the EMF,then the total voltage across the inductors terminals would be 0v,and no current would flow.

I agree. No potential difference, No current flow.

No, the device connected to the EMF source is the same device that manifests the CEMF.

There is no such thing as the EMF source connected to the CEMF source connected to the device.  That is the only possible way to have no potential difference.

i.e.;  <EMF> --> <CEMF> -->  <Device>

The above is NOT what is happening.

This is what you have:  The EMF source connected to the device.  At the same time the device itself is the source of the CEMF.

i.e.; <EMF> --> <Device>

Where <Device>  is also the source of the <CEMF> at the same time.

i.e.;  <EMF> --> <Device/CEMF>

MH,

CEMF, at least in my forest full of trees, has always been used to describe a particular mechanism, or action, specifically related to inductors, and less so with regard to electrochemistry.

As well, it would seem that any device capable of producing a CEMF exactly equal to an applied EMF would prevent current flow.

Consider two identical voltage sources connected in parallel (positive to positive, negative to negative).  One Vsource represents EMF and the other Vsource represents CEMF.  As long as both sources produce identical voltage, there will be no current flow. 

I think you will need to do a bit better with regard to finding a reference relating CEMF to the action of a resistor...
