What type of magnet depends on flowing current to produce a magnetic field?
A) electromagnet
B) permanent magnet
C) temporary magnet
D) domain magnet
Electromagnet
A type of magnet where the magnetic field is produced by an electric current, typically through a wire wound into a coil around a magnetic core.
Magnetic Field
An invisible field around magnetic materials where magnetic forces are exerted and can be detected by other magnetic materials or moving electric charges.

Final Answer :
A
Explanation :
Electromagnets depend on flowing current to produce a magnetic field. When the current flows through a wire coil, it generates a magnetic field. The strength of this field can be adjusted by changing the current's intensity or by modifying the coil's properties, such as the number of turns in the coil. Permanent magnets, temporary magnets, and domain magnets do not rely on an external electric current to maintain their magnetic properties.
