An electric current passing through a conductor generates a magnetic field.
A long coil of wire generates a magnetic field similar to that of a bar magnet, with field lines running parallel to the coil's axis. This type of magnetic field is known as a solenoidal field and is strongest inside the coil, as the magnetic field lines are tightly packed together.
An electromagnet is produced by an electric current. When an electric current flows through a coil of wire, it generates a magnetic field. The strength of the magnetic field can be controlled by adjusting the amount of current flowing through the coil.
An electromagnetic field is caused by electric charges in motion. When charged particles move, they create a type of energy called electromagnetic radiation, which generates an electromagnetic field. This field consists of both electric and magnetic components, propagating outwards from the moving charges.

The setup you described creates an electromagnet. When a current flows through the wire, it generates a magnetic field around the iron nail, temporarily magnetizing it. The strength of the magnetic field can be controlled by adjusting the amount of current flowing through the wire.

Solenoids are made up of electromagnets. These electromagnets consist of a coil of wire that generates a magnetic field when current passes through it. This magnetic field can be used to move a plunger or armature within the solenoid.

Part of the electromagnetic spectrum can be detected by eye, and we call that bit "light". The thing about electromagnetic radiation is that a varying magnetic field causes a (varying) electric field (that's how power stations make electric current) and a varying electric field causes a (varying) magnetic field. So electromagnetic radiation is what you get when a varying electric field creates a varying magnetic field which in turn contributes the varying electric field. The whole thing then appears as bundled varying electric and magnetic field wave system which propagates at the velocity of light, That is why it is called electromagnetic. There are no magnetic poles or electric charges in it, and it can travel through a vacuum.
It takes some energy to build up a magnetic field; when the magnetic field collapses, the same amount energy is released again. So, it makes sense to consider that somehow, energy is stored in the magnetic field.
An electromagnet is a type of magnet in which the magnetic field is produced by the flow of electric current. The magnetic field disappears when the current ceases.-wikipedia

The answer to this question depends on many factors. These include what type of coil is being used, what solution is in the tank, what is the purpose of the activity and what the desired outcome may be.
When materials are placed in a magnetic field, they can exhibit various magnetic properties such as attraction or repulsion, alignment of magnetic dipoles, and induction of a magnetic field in the material itself. These properties depend on the type of material and its composition, as well as the strength and direction of the magnetic field applied to it.
