Depending on how long the battery is attached, the magnetic field will linger in the electromagnet. The amount of coils will also prolong the magnetism for a bit of time. SO the magnetic field will leave fast unless the battery has been attached for a while and if it has a lot of coils.
Does the magnetic field leave an electromagnet fast or slow? explain..

Electricity and magnetism are closely related. Flowing electrons produce a magnetic field, and spinning magnets cause an electric current to flow. Electromagnetism is the interaction of these two important forces.

Electromagnets need an electric current to generate a magnetic current, electromagnetics can be turned on and off, you can increase or decrease the strength of an electromagnet by increasing or decreasing coils
Give three examples of how electromagnets are different than permanent magnets.
