What is the importance of magnetism in electrical devices?
Magnetism is important in electrical devices because it allows for the generation of electricity through electromagnetic induction. This enables the operation of devices such as generators, motors, transformers, and speakers. Additionally, magnetism is essential for the function of components like magnetic storage devices (hard drives, credit cards) and magnetic sensors.
What is residual magnetism?
Residual magnetism is the magnetism that remains in a material even after an external magnetic field is removed. This phenomenon is commonly observed in magnetic materials such as iron and steel after they have been magnetized. Residual magnetism allows these materials to retain some magnetization and can be useful in applications such as magnetic memory storage devices.
Why do you need magnetism in your lives?
Magnetism is crucial for many aspects of modern life, including generating electricity, powering devices like electric motors and generators, and enabling technologies like MRI machines for medical imaging. It plays a key role in numerous everyday objects like speakers, credit cards, and magnetic storage devices. Without magnetism, our lives would lack the convenience and functionality that many of us take for granted.
What devices are based on the magnetic effect of current?
Devices such as electric motors, transformers, inductors, and magnetic-based sensors utilize the magnetic effect of current. These devices rely on the interaction between electric current and magnetic fields to operate effectively in various applications.
What is difference between residual magnetism and retentivity?
Residual magnetism and remanence are the same thing. The term residual magnetism is often used in engineering applications. Both terms describe the magnetization, and measure of that magnetism, left behind in a ferromagnetic material after the external magnetic field is removed.
What are devices that work because of earths magnetism?
Electromagents

Does microphone needs magnetism to operate?
No, microphones do not require magnetism to operate. Microphones work by converting sound waves into electrical signals using a diaphragm or a transducer, which doesn't rely on magnetism to function.
What is a geological event that is not dangours?
The reverse of the earths magnetism is not dangerous to humans as we do not rely on magnetism to guide us anymore. It will cause mass extinction of birds though.
What are three types of paleomagnetism?
dia, para, ferro magnetism
What types of magnets are harder to magnetism much longer?
cook
What would happen if Michael Faraday did not discover magnetism?
If Michael Faraday did not discover magnetism, our understanding of electricity and magnetism as interconnected forces may have been delayed. This could have hindered the development of important technologies like electric motors, generators, and transformers, which rely on the principles of electromagnetism for their operation.
What are the computers and mobile devices on the network that rely on the server for its resources?

Which devices on Table 3 are powered entirely or partially by electromagnetic induction (the phenomenon of a changing magnetic or electric fields effect on electricity or magnetism)?
The devices on Table 3 that are likely powered by electromagnetic induction include wireless chargers and some electric toothbrushes that use inductive charging technology. These devices rely on the principle of changing magnetic fields inducing an electric current to charge their batteries without the need for direct electrical connections.
