... (Yes. When the current is switched off, the magnetic field goes away, and the nail is no longer a magnet. Sometimes, the nail will drop most, but not all of the paper clips. In this case, the nail has become a very weak temporary magnet due to the induced magnetic field from the current in the wire. ...
