It's not working because you're not telling -replace what to put in place of \n. Try:

-replace "`n",";"

OR

Use Get-Content to read the contents into a collection of lines; you can then join that collection (array) with the -join operator into a single string.

$variabl1 = (Get-content -path "e:\abc1.txt") -join ";"

thanks for your suggestion but the last ; i m missing...like the output should be user1;user2;user3;user4; if there are 4 entries in the file upto user4

Then append a semicolon at the end of the string. You'd have to do the same thing if your input file didn't have a trailing newline.
