Only while the magnet is entering or leaving the loop. If you hold it still, no current is generated. The same goes for a longer magnet where the loop is being moved, but the magnet always remains inside the loop; no current.
Simple. With a magnet. The iron dust will simply be attracted to the magnet. To collect the iron dust neatly, get a plastic sandwich bag or a small plastic baggie, put the magnet inside, use it to collect the iron dust, then turn the bag inside-out and remove the magnet.
Pretty much any electronics with wires. The metal inside the wires and generally attracted to the magnet. For example, it is a TERRIBLE idea to put a magnet next to or on a computer or computer monitor. It will distort anything and everything inside the computer.
There is a digger like veichle, but instead of a digger it is a humongous magnet on it. The person inside controls the magnet to pick up all the steel and the magnet is so strong that it magnetises it. Hope this helped!

A magnet has both a South pole and a North pole. The magnetic properties of a magnet come from the alignment of electrons inside of the magnet. The North pole of a magnet will repel another North pole, but attract a South pole, and vice versa.
