WebThe electromagnets are temporary magnets that are created when the electricity passes through a metal wire coil. When electricity passes through the metal coil, the electric field creates the magnetic field at the core or centre of the coil. This magnetic field can be made more powerful by introducing an iron rod in the centre of the coil. WebRT @ifindkarma: “When they slaughtered Congress, we didn’t wake up.
