Electromagnetism is a physical science that studies the electromagnetic force which thus exists respectively electrical charges. It should be the sum of all magnetic as well as electrical forces that act around energetic particles.
Several more home appliances for domestic purposes rely on electromagnetism as either a fundamental underlying operation.
Maglev trains, also known as high-speed trains, operate upon that electromagnetism concept.
Example: If positive charges move inside cables, they produce a magnetic field, as well as the direction and force, which could be ascertained using the Right-hand Rule.
