Answer 1

Answer:

If the guy uses a big permanent magnet for the job. The problem will be that after the metallic object have attached themselves to the magnet it would be difficult or near impossible to remove them from the strong attractive force. But if an electromagnet is used the items can easily be removed by switching off the current supply. And about how to persuade him.. politely maybe

Hope it helps..

Soln=Electromagnet will be more good than a permanent magnet.
