Introduction: Electromagnet

About: WHY!!!!! Would the computer companys put gold in the computers and electronic equipment. Because gold does not oxidize and is a great conductor… In connectors they use gold because the connectors must be ba...

Electromagnets means magnetism caused by an electric current flows through a conductor in an object means that if we let her. Current flowing in the conductor will cause. Magnetic field around the conductor when an electric current flows through the wire. Will take place around the magnetic field lines. Wire conductor But magnetism occurs only a small amount. Which can not be put to good use. To increase the intensity of the magnetic field. Achieved by bringing the wire conductor is wrapped into a coil. Magnetic field generated in each section of the wire conductor is extra power. Made up of the magnetic needle.
