The term 'electromagnet' is often used in technical and scientific contexts, not in everyday conversation.

Technical Usage

An electromagnet is temporary; it only has a magnetic field when electric current is flowing.

Temporary Magnetism

Electromagnets can lift heavy metal objects, which is highly useful in industries like scrap metal management.

Powerful Tool

Use 'electromagnet' in scientific discussions or academic papers dealing with physics or engineering.

Academic Context

Understanding electromagnets helps in grasping fundamental concepts of physics like electromagnetism.

Physical Principle

Electromagnets serve as key components in various devices, ranging from simple to complex machinery.

Versatile Component

 The gel that you're holding would be lining the bottom of the board. Now this is important for two reasons. the soft properties of the magnet that make it so that, if it were to hit the rider in the head, it wouldn't injure him. In addition, you can see from the diagram on the right, the underpart of the slide would be an electromagnet. So this would actually repel the rider a little bit as you're going down.

 turning the planet into a giant electromagnet. This phenomenon also creates a protective layer around the planet that shields us from the most harmful radiation in space leaving us to enjoy a world held together by the strange and fundamental force of electromagnetism.

 Data is written onto the disc by converting strings of bits into electrical current fed through an electromagnet. This magnet generates a field strong enough to change the direction of the metal grain's magnetization. Once this information is written onto the disc,
