Lets assume we have a custom list "test1" which has a choice field "Choice". The values for the choice field are "A", "B","C" & "D".
If you create a Choice column through UI the default value will be selected as "A".
In this we will be seeing how to change the choice field default value to null using powershell
$site = Get-SPSite "http://serverName:1111/sites/sample "$web=$site.Rootweb$list = $web.Lists.TryGetList("test1")$field = $list.Fields["Choice"] $field.DefaultValue = $null
$field.Update()
$list.Update()
