Describe the concept of magnetic field and its ... - SS1 Physics Magnetism and Electromagnetism Question

A magnetic field is a region in which a magnetic force can be detected. It is created by moving electric charges or by the presence of magnets. The properties of a magnetic field include direction, strength, and magnetic field lines.

The direction of a magnetic field is indicated by the north and south poles of a magnet. The strength of the magnetic field is determined by the proximity of the magnetic source. Magnetic field lines are imaginary lines that depict the direction and strength of the magnetic field. They form closed loops around a magnet, and the density of the field lines represents the strength of the field.
