any three ways to produce temporary magnetic field are:
* use a permanent magnet any bar magnet or ring magnet
* by using electromagnets which can produce magnetic field when we pass current through them
* or by using a copper wire and some electricity source we can make our own temporary magnet.in this process we have to make a continuous loop of pure copper wire on a iron bar or a screw and attach batteries to both the end of the wire.
electromagnatism
* electromagnets work when we pass some electricity through it
as electromagnets contain pure insulated copper wire coiled around a iron ring or etc usually copper don't attracts magnet but when we pass some electricity through it it behaves like a magnet.[by using these principle our fans motors and many other electric rotatory machines work.]
