Temporary magnets are distinguished from permanent magnets by their ability to turn and off. Electromagnts, for instance, rely on an electrical current to generate a magnetic field. Electromagnets have a north and south pole just like their permanent counterparts. The position of an electromagnet’s...
The archetype electromagnet is the crane-operated model that picks up automobiles and scrap metal by the ton. This model demonstrates one of the desirable features of the electromagnet--it becomes a magnet or not a magnet at the flip of a switch. The electric current running around an iron c...
Atoms become imbalanced by the loss or gain of atoms. When atoms loose these electrons, they are positively charged; when they gain electrons they are negatively charged. Once an atom stops being considered a neutral atom by either becoming a positive or negative atom, this creates static electr...

For example, when you push the button on a TV remote to watch TV, it sends an electrical signal to the “relay” inside the TV, turning the main power ON. There are various types of relays used in many applications to control different amounts of currents and number of circuits. ...
Electromagnetic waves are simultaneous periodic oscillations in the intensity of an electromagnetic field. Unlike traditional waves, they do not need a medium to travel through, and they travel at the speed of light. There are seven types of electromagnetic waves: radio waves, microwaves, infrared ...
Magnet is defined as a material that can produce its own magnetic field. There are three types of magnet: permanent magnet, temporary magnet, and electromagnet. Magnets are used in electric bells and generators.
In an electromagnet, the flow of atoms through the wire helps create the magnetic field for the electromagnet. When looking at a simple electromagnet,... See full answer below. Learn more about this topic: Electromagnet | Definition, Parts & Uses ...
What are the differences between a motor and a generator? What is an electric motor? Give name of its different parts and also explain their functions. How does electromagnetism relate to an electric motor? What is the basic difference between an electric generator and an electric motor? What ...
