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 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 is the difference between magnetism and electricity?
The difference between electricity and magnetism is that you must be in the same frame of reference as the electric field to experience electricity, because all that magnetism is, is electricity moving relative to you.Although they are two different forms of energy, you can use magnetism to create electricity and you can use magnetism to create electricity.Electricity is the flow of energy or current through a metallic substance. Magnetism is the attraction of the metallic molecules in a solid or substance.
What is the sure test of magnetism?
The sure test of magnetism is the ability of a material to attract iron or other magnetic materials. If a material attracts iron, it is considered to be magnetic.
Which branch of science includes magnetism?
Physics is the branch of science that includes the study of magnetism. Magnetism falls under the broader category of electromagnetism, which deals with the interactions between electric and magnetic fields.
Is electromagnets are natural magnets?
The magnetism of an electromagnet is natural (it comes out of the laws of physics), but the magnetism disappears when the electricity is turned off - it is not a permanent magnetism.
Give some picture of the one who invented electricity?
No-one "invented" electricity. It is a natural force. However many people discovered its nature and laws, and it was Michael Faraday who realised the relationships between electricity and magnetism, hence making possible the generation of electricity, and the electric motor.
What do you call laws that are based on customs and passed down from generation to generation?
Grandfathered unless there is a proper term for it !?!?
Which of these is not a way by which objects can become charge?

What is permanent magnetism?
Permanent magnetism is magnetism that is permanent. I think...

How initially voltage build up in an alternator by residual magnetism?
The residual flux will help the phenomenon of changing flux. So that emf generation takes place.

What is the difference between electromagnetism and magnetism?
Magnetism is a natural force that causes certain materials to attract or repel each other, whereas electromagnetism involves the interaction between electric currents and magnetic fields, resulting in the generation of a magnetic field. Electromagnetism can be controlled and manipulated through the use of electric currents, while magnetism exists naturally in materials without external influence.
Is magnetism a solid?
Magnetism is a force not a solid.
