Basic Concepts of Electromagnets
Electromagnets are based on the fundamental principles of electromagnetism, which describes the relationship between electricity and magnetism. When an electric current flows through a wire, it creates a magnetic field around the wire. The strength of the magnetic field depends on the amount of current flowing through the wire and the number of turns in the coil.
Electromagnets are the backbone of electric motors, which are the workhorses of the construction industry. Electric motors are used to power everything from cranes to hoists, lifting heavy building materials to great heights. Electromagnets, with their ability to generate powerful magnetic fields, are essential for creating the torque that drives these motors.
Without electromagnets, these vital construction tools would be powerless.
