I'm looking to get a full understanding of what makes them work, any suggestions for some one not so familiar with the subject.
An electromagnet is a type of magnet that is created by passing an electric current through a coil of wire. The electric current creates a magnetic field, which allows the electromagnet to attract or repel other objects made of magnetic materials.
Electromagnets work by using electricity to create a magnetic field. When an electric current flows through a wire, it creates a circular magnetic field around the wire. By coiling the wire, the magnetic field is amplified, creating a stronger magnet. This magnetism can be turned on and off by controlling the electric current.
Electromagnets have a wide range of uses, including in motors, generators, speakers, and magnetic levitation trains. They are also used in medical devices, such as MRI machines, and in industrial settings for lifting and separating metal objects.
You can find literature on electromagnets by searching online databases, such as Google Scholar or JSTOR, using keywords such as "electromagnet," "magnetic field," or "electromagnetic theory." You can also consult textbooks or scientific journals related to physics or electrical engineering.
Some key concepts to understand when researching electromagnets include the relationship between electricity and magnetism, the factors that affect the strength of an electromagnet, and how electromagnets are used in different devices. It is also important to understand the properties of magnetic materials and how they interact with electromagnets.
