    I have 18-awg enamel magnet wire and I was wondering what the maximum current I should use is such wire is. Thank you.

    Are you planning to wind this into some sort of coil? That's what magnet wire is normally used for.

    If so, you'll want also (in addition to Warren's good link) to look at the temperature rating of the enamel; you may need to derate the NEC table accordingly.

    At what frequency are you planning to use this? If much higher than 60 Hz, you'll again want to apply a derating factor.
