Jul 24, 2024 · A magnet is a material or object that produces a magnetic field. This magnetic field is invisible but is responsible for the most notable property of a magnet: a force that pulls on other ferromagnetic materials, such as iron, steel, nickel, cobalt, etc. and attracts or repels other magnets.
Jul 22, 2024 · Faraday's law of induction - Wikipedia. Faraday's experiment showing induction between coils of wire: The liquid battery (right) provides a current which flows through the small coil ( A ), creating a magnetic field. When the coils are stationary, no current is induced.
