A magnetic field is an invisible force field that surrounds a magnet or any moving charged particle. It is created by the movement of electrons within an object and can be detected by its effect on other objects.
Magnetic fields are created by the movement of electrically charged particles. This can occur in several ways, such as the movement of electrons in an electric current or the spinning of an atomic nucleus.
Magnetic fields can either attract or repel each other depending on the orientation of their poles. Like poles (north and north or south and south) will repel each other, while opposite poles (north and south) will attract each other.
The force exerted by a magnetic field on a charged particle is known as the Lorentz force. This force is perpendicular to both the direction of the magnetic field and the direction of motion of the charged particle.
Magnetic fields have many practical applications in our daily lives, such as in compasses for navigation, in electric motors and generators, and in medical imaging devices like MRI machines. They are also used in data storage devices like hard drives and credit cards.
