Iron shavings ,compass and galvanometer use to determine the direction of the magnetic field lines around a magnet.
What is electromagnet?
An electromagnet is a magnet whose magnetic field is generated by an electric current. Wire coiled into a coil is used to make electromagnets.
A current flowing through the wire produces a magnetic field that is focused in the hole.
A tiny compass may be used to map out magnetic field lines. As illustrated, The compass is moved from point to point around a magnet, with a small line drawn in the direction of the needle at each point.
The course of the magnetic field line is then shown by joining the lines together.
Hence, iron shavings ,compass and galvanometer use to determine the direction of the iron magnetic field lines around a magnet.
