Magnetism is a natural force that causes objects, such as iron, to attract or repel one another. It is caused by the movement of electrons within a material.
An electromagnet is a temporary magnet that is created when an electric current passes through a wire wrapped around a magnetic material, such as iron. The strength of the electromagnet can be controlled by changing the amount of current flowing through the wire.
When an electric current flows through a wire, it creates a magnetic field around the wire. The direction of the magnetic field depends on the direction of the current flow.
A permanent magnet is a material that produces a magnetic field without the need for an external source, while an electromagnet requires an electric current to produce a magnetic field. Additionally, the strength of a permanent magnet cannot be easily changed, whereas an electromagnet's strength can be controlled by adjusting the current flow.
Magnetism is used in a variety of everyday objects and technologies, such as speakers, motors, and generators. It is also used in magnetic compasses for navigation, MRI machines in healthcare, and credit/debit cards for data storage.
