Introduction to Electromagnetism and its Applications

The video tutorial explains the production of magnetic fields around wires and solenoids, highlighting how current affects field strength. It describes the properties of solenoids, including their strong and uniform magnetic fields, and compares them to bar magnets. The tutorial explores practical uses of electromagnetism, such as in electromagnets for lifting materials, circuit breakers for safety, and electric bells for signaling. Each application demonstrates the principles of electromagnetism in everyday devices.
