Electromagnetism: A Force Shaping Modern Technology
Imagine electricity and magnetism as two parts of the same superpower called electromagnetism!
It's a force that helps build everything around you.
Long ago, Ben Franklin proved lightning is electricity.
Scientists later found that electricity and magnetism are connected.
This force helps magnets stick, runs your phone, and lights your house.
Over time, scientists like Maxwell and Einstein helped us understand this force and the modern world.
Quantum electrodynamics further explained how tiny particles 'talk' using light, creating the foundation of today's technology.
Electromagnetism combines electricity and magnetism into a single force.
Benjamin Franklin proved that lightning is electricity via his kite experiment.
Michael Faraday created the first electric motor in 1821.
James Clerk Maxwell showed light itself is an electromagnetic wave.
Electromagnetism is fundamental to technology and daily life, from transport to medicine.
