What is a Solenoid

It is a coil containing many circular turns

These wires are wrapped carefully in the shape of a cylinder.

It seems like

If we move current via the circuit, the magnetic field would be shown as

Let's look at some houses of Magnetic Field produced in Solenoid

Solenoid behaves like a bar magnet

A solenoid behaves like a bar magnet when current is passed through it.

Like in bar magnet, the field traces emerge from one finish and merge into some other.

In a solenoid, the field strains behave in the same approach

One finish of Solenoid behaves as Magnetic North Pole

and Other finish as Magnetic South Pole

Field traces are parallel immediately strains within solenoid

It means magnetic field is same at all issues within the solenoid,

that is, magnetic field is uniform inside a solenoid.

Magnetic Field Produced is Strong in a Solenoid

A solenoid has numerous turns

More the selection of turns, more the current flows through it and hence more the magnetic field

Hence, they are used to make electromagnets

Strength of Magnetic field in a Solenoid relies on

Strength of Magnetic field in a Solenoid depends on

Number of turns in the solenoid - More number of turns, higher the magnetic field Strength of current in the solenoid - More current, extra the magnetic field Nature of Core Material used inside the solenoid - If we use cushy iron inside the solenoid, it produces the strongest magnetism

What is an Electromagnet

An electromagnet is a magnet consisting of twine would round a soft iron core.

It is magnetized most effective when electric current is handed via the coil.

Example

A cushy piece of iron is placed inside solenoid

When electric current is passed, sturdy magnetic field is created.

The iron turns into magnetic due to the strong magnetic field of the solenoid.

The magnet so produced is referred to as electromagnet

Note : Only cushy iron is used to make an electromagnet as a result of Core of an Electromagnet loses all its magnetism when current is switched off.

That is why steel is now not used to make electromagnets - It does not lose all its magnetism when current is switched off
