Magnetic and electrical fields are related, and magnetism, along with gravity and strong and weak atomic forces, is one of the four fundamental forces in the universe. But none of those facts answers the most b
Most MRI systems use a superconducting magnet, which consists of many coils or windings of wire through which a current of electricity is passed, creating a magnetic field of up to 2.0 tesla. Maintaining such a large magnetic field requires a good deal of energy, which is accomplished by supe...
Electricity and magnetism are both non-contact forces. This means that they both create fields that can influence objects at a distance. We can observe this as a magnet approaches a magnetic substance and suddenly pulls it closer.Answer and Explanation: ...

While this action may sound complicated, it's actually very simple: The reaction in the anode creates electrons, and the reaction in the cathode absorbs them. The net product is electricity. The battery will continue to produce electricity until one or both of the electrodes run out of the ...
The electricity magnetizes the electromagnet. Increasing current boosts the electromagnet's magnetic force, and decreasing current lowers the magnetism. When the current jumps to unsafe levels, the electromagnet is strong enough to pull down a metal lever connected to the switch linkage. The entire ...

Electricity and Magnetism- [designed for grades 6-8] an overview of electromagnetism - Students will construct an electromagnet at the end of the lesson Electricity and Magnetism- an elementary WebQuest about how electricity and magnetism are related ...
Electricity: Electricity is a phenomenon in physics that relates to the existence and movement of matter that contains a characteristic of an electric charge and is also nearly linked to magnetism. Answer and Explanation: Learn more about this topic: ...
Nearly all of our cells have the ability to generate electricity. And in this article, we'll look at the role of electricity in the human body and find out how we produce it in the first place. The starting point is simple: Right now, any cells in your body that aren't actively sen...
