To carry out the experiment, to observe the magnetic action of the current, you need to take a copper wire, which will be covered with an insulating material and wind it around an iron nail, and connect the ends of the wire to a current source. When the chain is closed, the nail will become a magnet and will be able to attract small iron objects to itself; if the circuit is opened, the nail will be demagnetized.
