No, at one mile there is no limit to the weight that could be supported;
though to hang ocean liners off the end you would need a rather thick cable.

The long version (along with lots of fun mathematics) can be found here:

It would generate an alternating current if rotation was parallel to the
axis of the Earth's magnetosphere. On a gut fielding, I don't think one mile
would generate enough power to be worth collecting, dangerous, or difficult
to insulate from, or heating efects.
