By passing a current threw it.
When copper wire is wrapped around a magnet, it creates an electromagnet. This increases the strength of the magnetic field produced by the magnet.
A solenoid magnet, which is a long coil of wire wrapped around a ferromagnetic core, has a similar magnetic field to that of a bar magnet. This is because the magnetic field created by the current flowing through the wire generates a magnetic field similar to that of a bar magnet.
A magnetic field is produced around a wire when an electric current flows through it. This magnetic field is directed along circular lines around the wire.
For electricity to be produced from a magnet, the magnet needs to move relative to a coil of wire, causing a change in magnetic field. This movement induces an electric current in the wire, generating electricity through a process called electromagnetic induction.
When a magnet moves near a wire, it creates a changing magnetic field around the wire. This changing magnetic field induces an electric current to flow in the wire through electromagnetic induction. The current is only induced while there is a relative motion between the magnet and the wire, or if the magnetic field intensity changes.

An electro magnet!
In layman's terms; a magnet has a natural magnetic field around it. This field interacts with iron based materials, like steel (but not stainless steel, or aluminum) and when a piece of steel is adjacent to the magnet's attractive pole, they stick together. When current (electricity) flows through a conductor (piece of wire) a magnetic field is produced, similar to a regular magnet. If a piece of wire (with current flowing through) is wrapped around a magnet, the Electromagnetic field that occurs around the wire joins and strengthens the magnetic field of the magnet, thus strengthening the overall magnetism. So when you see a crane picking up and dropping junk cars, they are simply turning on & off the flow of electricity through the coils of wire wrapped around the magnet doing the work.

Yes. The field lines of a bar magnet emerge from one end, curve around, and stop at the other end. The field lines around a current-carrying wire are circles, with the wire passing through their centers.

Magnetic field.
When a magnet moves near a wire, it creates a changing magnetic field around the wire. This changing magnetic field induces an electric current to flow in the wire through electromagnetic induction. The current is only induced while there is a relative motion between the magnet and the wire, or if the magnetic field intensity changes.
When you pass an electric current through a copper wire that is wound around a magnet, it creates a magnetic field that aligns with the magnetic field of the magnet. This process strengthens the overall magnetic field around the magnet, effectively increasing its power. This principle is the basis of how electromagnets work.
Electricity can be produced by moving a magnet through a wire coil, which induces a current in the coil. This process is known as electromagnetic induction and is the basis for how generators work to produce electricity. The moving magnetic field created by the magnet interacting with the wire coil creates an electric current to flow in the wire.
One way to increase the amount of electric current produced by a magnet is to increase the strength of the magnetic field. This can be done by using a stronger magnet or increasing the number of turns in the wire coil. Another way is to increase the speed at which the magnetic field changes, which can be achieved by moving the magnet or the wire coil faster.
