Answer:

an electronic magnet is a temporary magnet made by electric current

Explanation:

the correction of the current decides it's polarity

an Electromagnet is a temporary magnet whereas a permanent magnet is permanent

the strength of an Electromagnet is decided by the current as when a copper wire is rounded up on a iron piece then in the current passes to the copper wire if the current is in the direction then the direction coming will be south and the direction going will be north
