Increase the number of coils in the electromagnet. Use a stronger magnetic material in the core of the electromagnet. Increase the current flowing through the wire winding of the electromagnet.
To make an electromagnet stronger, you can increase the current flowing through the coil, increase the number of turns in the coil, or use a material with high magnetic permeability as the core of the electromagnet, such as iron.
A compass can be used to determine the direction of the magnetic field in an electromagnet. The needle of the compass will align along the direction of the magnetic field lines produced by the electromagnet.
Increase the number of coils in the wire, increase the current flowing through the wire, and use a stronger magnetic material for the core of the electromagnet.
The strength of an electromagnet is proportional to the number of turns in the coil, the amount of current flowing through the coil, and the magnetic permeability of the core material used in the electromagnet. Increasing any of these factors will increase the strength of the electromagnet.

both are magnetic, both can be used to produce an electric current if around a wire
Increase the number of coils in the electromagnet. Use a stronger magnetic material in the core of the electromagnet. Increase the current flowing through the wire winding of the electromagnet.
All electric motors are electromagnets.

I'm not sure where a bar magnet is used, but an electromagnet is used in junkyards, and in some laboratories.
Electro Magnetic is correct
Electromagnets are widely used now. Instead of traditional magnets.
A compass can be used to determine the direction of the magnetic field in an electromagnet. The needle of the compass will align along the direction of the magnetic field lines produced by the electromagnet.
