What happens to an electromagnet when electricity runs through it?

∙ 13y ago
When an electric pulse runs through an electromagnet, the current travels in the electromagnets coils, causing a magnetic field to be developed inside and outside of the coils. The amount of coils, tightness of the coils, and the space between the coils are all very important factors in the production of said EM field.

What is an electromgnet?
An electromagnet is a magnet that runs on electricity. Unlike a permanent magnet, the strength of an electromagnet can easily be changed by changing the amount of electric current that flows through it. The poles of an electromagnet can even be reversed by reversing the flow of electricity.
How is hydroelectricity gathered?
The water runs through turbines and, this mechanical energy is transfered to generator which inturn is transfered into electricity for homes, businesses, and other things that need electricity.
How does a car scrap heap magnet work?
Scrap Heap MagnetUsually the kind of magnet a junkyard uses is an electromagnet. An electromagnet is simply an iron core wrapped around by copper wire. Then current runs through the wire, it becomes a very strong magnet. There are other types, but I think electromagnet is the most common for car scrap heap.
When electricity runs through light bulb what other type of energy is produced?
Light, heat, sometimes sound.
How is electricity useful and dangerous?
Electricity is useful because it...... * Runs the air conditioner * Runs the stove * Runs the computers * Runs the phones * Runs the washing machine Electricity is dangerous because it can kill you if you get shocked by too many volts worth.

Is a refrigerator magnet electromagnetic?
IT is different because an electromagnet runs with electricity. A refrigiator does not run with electricity.
What kind of magnet is electromagnet?
An electromagnet is a piece of iron(usually a cylinder or rectangle)wrapped around with copper wire that when electricity runs through it it works like a magnet. Also called artificial magnet.

What happens when a charger is plugged into a wall?
Electricity runs through it to charge your phone ect. :)
What happens in the arteries?
The blood runs through them
How Electric Motors Work?
Many people are not aware of the fact that electric motors exist all around them. They are used in their car, washing machine, food processor, and so on. Even fewer people are aware of the way in which an electric motor actually works. Here are some of the basics. An electric motor is powered by the forces of electricity and magnetism. Magnets are used in order to create motion. Consider a simple magnet, with a north and south pole. The fact that a pole is attracted by its opposite and repulsed by the same is utilized in order to create the motion inside of an electric motor. The heart of the electric motor is the rotor, which is an electromagnet. An electromagnet consists of copper wiring that has been wound in a circle. When electricity moves in a circle, it creates a magnetic field. When electricity moves through the coil of wire, it becomes a magnet. When electricity is not passing through it, it is simply a coil of copper wiring. Inside an electric motor, there is at least one permanent magnet. When the electromagnet is activated, the north pole of the permanent magnet faces the north pole of the electromagnet. The permanent magnet is attached to an arm that can rotate around the electromagnet. Since the permanent magnet is repulsed by the north end of the electromagnet, it swings around to the other side. The direction of the electricity through the electromagnet is then reversed. This causes the north end of the electromagnet to become the south end. When this happens, the permanent magnet against swings over to the other side. This is the basic principle behind how all electric motors work. There are two basic types of electric motors: those that run on alternating current and those that run on direct current. A motor that runs on alternating current can take advantage of the fact that the direction of the electricity is constantly reversing in order to constantly reverse the polarity of the electromagnet and keep the electric motor running. In the case of direct current, a device known as a commutator is used in order to switch the direction of the current back and forth.
How does an electric fence unit work?
A generator runs electricity through a wire thus electrifying it.
How does tidal energy produce heat and eletricity?
tidal electricity is simply a turbine that runs underwater and when it turns with the ebb tide it creates electricity. Then it carries the electricity through pipes back to land
What are different parts of hydro energy?
Water runs through a channel, either natural or built.The water spins an electricity turbine in the channel, producing electricity.
How is hydroelectricity gathered?
The water runs through turbines and, this mechanical energy is transfered to generator which inturn is transfered into electricity for homes, businesses, and other things that need electricity.
