Ответ:
The nail has become a temporary magnet, while the bar magnet remains a permanent magnet.
Explanation:
When the bar magnet takes off the nail, it magnetizes the nail. The fingerprint domains are temporarily aligned in one direction and act as a magnet. The nail becomes a temporary magnet. Therefore, when the tip of the nail hits a few staples, the lead attracts the nail and sticks to it.so correct option is b. The nail has become a temporary magnet, while the bar magnet remains a permanent magnet.Ответ:
