[Current through a coil in a DC circuit]

Another way would be to derive the current by the number of turns of the coil. Deriving the current by the resistance is not possible you guys say? due to the AC current. I have a spare motherboar with the same coil that i can unsolder. I can use it to measure the characteristics if needed.

The only option I have is to use a Hall Effect sensor I think, but thats my last solution because i have to place it inside a computer. THere is a great chance that interference will occur.

[Current through a coil in a DC circuit]

In this case we are talking about DC current. I want to design a circuit that enables me to log the DC current that flows through the coil.

Therefore I need a measurement method to measure the current.

[Current through a coil in a DC circuit]

I would like to measure the current through a coil in a DC circuit, but I'm not sure how to accomplish this. I cannot put a sense resistor in between and the coil is my only option to indicate for the current. I was thinking about measuring the voltage over the coil, but I'm not sure how the voltage relates to the current for this coil.

Do you have any ideas?
