An electromagnet uses an electromagnetic field to generate a magnetic field when an electric current flows through it.
Electromagnetic waves consist of an electric field and a magnetic field that oscillate perpendicular to each other and to the direction of wave propagation. These two fields work together to carry energy and information through space.
Electric field and magnetic field
Electromagnetic induction is used in a wide range of applications, including generators to produce electricity, transformers for voltage regulation, induction cooktops for heating, and wireless charging technologies for electronic devices. It is also the principle behind how electric motors work.
Antennas work by converting electrical signals into electromagnetic waves for transmission, and vice versa for reception. When a signal is sent through the antenna, it creates an electromagnetic field that propagates through space. This field can be picked up by another antenna tuned to the same frequency, allowing for communication.
Electromagnetic induction is the process of creating an electric current in a conductor by moving it through a magnetic field or by changing the magnetic field around it. This movement or change in magnetic field induces a flow of electrons, generating electricity. This principle is used in devices like generators to produce electrical power.
Part of the electromagnetic spectrum can be detected by eye, and we call that bit "light". The thing about electromagnetic radiation is that a varying magnetic field causes a (varying) electric field (that's how power stations make electric current) and a varying electric field causes a (varying) magnetic field. So electromagnetic radiation is what you get when a varying electric field creates a varying magnetic field which in turn contributes the varying electric field. The whole thing then appears as bundled varying electric and magnetic field wave system which propagates at the velocity of light, That is why it is called electromagnetic. There are no magnetic poles or electric charges in it, and it can travel through a vacuum.

it uses a radio wave as it has a big wave length. it is an electro magnet that needs to be heated to work.

The process by which a substance, such as iron or steel, becomes magnetized by a magnetic field. The induced magnetism is produced by the force of the field radiating from the poles of a magnet.
An EMF detector is a device that measures electromagnetic fields. It works by detecting the presence of electromagnetic radiation in the surrounding area. The detector uses sensors to pick up on the strength and frequency of the electromagnetic fields, providing a reading that indicates the level of exposure to these fields.

An electromagnetic accelerator uses magnetic fields to push and propel objects at high speeds. When an electric current flows through a coil of wire, it creates a magnetic field. By rapidly switching the direction of the current, the magnetic field pushes and pulls on a metal object, accelerating it forward. This process can propel objects at very high speeds, making it useful in applications like railguns and coilguns.
Diction is defined as the words an author uses in a literary work as part of a literary style.
The induced electric field tends to oppose the change in magnetic flux that causes it, in accordance with Faraday's law of electromagnetic induction. This conservative nature of the induced electric field ensures that the total electromagnetic field obeys the principle of conservation of energy. This property is fundamental for understanding electromagnetic phenomena and plays a crucial role in various applications, such as transformers and electric generators.
