Old PDF: "Motors are simple." Updated PDF: "Permanent magnet synchronous motors (PMSM) in a Tesla use neodymium magnets so strong they can crush a finger. Regenerative braking is just a motor running backwards as a generator." : These four mathematical laws unify electricity and
When an electric current flows through a wire, it automatically generates a magnetic field around that wire. The Right-Hand Rule Old PDF: "Motors are simple
“High voltage is always dangerous.” Truth: A Van de Graaff generator (50,000V) gives a tiny sting. A 12V car battery (low voltage) can melt a wrench and cause burns. Current kills, not voltage alone.
: A region created by charged particles that exerts a force on other charges. Field lines move away from positive charges and toward negative ones. Magnetic Field
The electromagnetic force is a fundamental force of nature that acts between charged particles. It's a vector force, meaning it has both magnitude and direction. The electromagnetic force is responsible for:
