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 basic question: What exactly makes a magnet stick to certain metals? Or why don't...
You probably know that magnets attract specific metals and they have north and south poles. Opposite poles attract each other while like poles repel each other. Magnetic and electrical fields are related, and magnetism, along with gravity and strong and weak atomic forces, is one of the four ...
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: ...
Electricity and Magnetism Inquiry Card - How Do You Listen to Your Music?
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...

Magnets, Electricity, and Inductive Coupling To understand how a wireless charger works, we need to take a look at how magnetism and electricity are related. It's a relationship that makes possible hundreds of different types of electronic devices!
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 ...
