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.

The easiest is to align the object with the earth's magnetic field and pound on it with a hammer, but this is slow. Another is to rub one pole of a magnet repeatedly in the same direction along it. The fastest is to place it inside an electromagnet solenoid and power the electromagnet from a DC power source.
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.
Increase the number of coils in the electromagnet. Increase the current flowing through the wire. Use a core material that is easily magnetized, such as iron or steel.
Increasing the number of turns of wire in the coil will increase the magnetic field strength. Using a core material with high magnetic permeability, such as iron, can enhance the strength of the electromagnet. Passing a larger electric current through the coil will generate a stronger magnetic field.
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.
Increasing the number of coils in the wire winding around the core and increasing the current flowing through the wire are two ways to increase the strength of an electromagnet. Both of these factors contribute to creating a stronger magnetic field in the core, increasing the electromagnet's overall strength.
There are many ways to do permanent hair straightening. Some of the ways to do permanent hair straightening includes using the EasyStraight hair system, using the KertatinPerfect hair system, and undergoing salon treatments.
They are two ways of expressing the same number: three billion (3,000,000,000).
