Magnets in electric motors create a magnetic field that interacts with the current-carrying coil, producing rotational motion. This interaction between the magnetic field and electric current is fundamental to the motor’s operation.
The Earth’s magnetic field is a natural magnetic field generated by the movement of molten iron in the Earth’s outer core. It protects us from solar radiation and aids in navigation using compasses.
Temperature affects magnetism by altering the alignment of magnetic domains. At high temperatures, thermal energy disrupts this alignment, reducing a magnet’s strength. Extremely high temperatures can even demagnetize a material.
