What magnet keeps its magnetism for a long time?
Neodymium magnets are known for retaining their magnetism for a long time due to their strong magnetic properties. They are commonly used in various applications where long-term magnetism is important, such as in electric motors and generators.
Who discovered magnatism?
The ancient Greeks observed magnetism in lodestone, but the modern understanding of magnetism is credited to William Gilbert, an English scientist who conducted experiments and published the first significant work on magnetism in 1600.
What term is used to describe the interaction between electrical energy and magnetism?
The term used to describe the interaction between electrical energy and magnetism is electromagnetism. This phenomenon occurs when an electric current produces a magnetic field and vice versa, as described by Maxwell's equations.
How do you measure magnetism and what tools are used for this purpose?
Magnetism is measured using a device called a magnetometer, which detects the strength and direction of magnetic fields. Some common tools used for measuring magnetism include Hall effect sensors, fluxgate magnetometers, and SQUIDs (superconducting quantum interference devices). These tools help scientists and engineers understand the properties of magnets and magnetic materials.
How long does it take for a magnet to lose its magnetism?
The time it takes for a magnet to lose its magnetism can vary depending on factors like the type of magnet and how it is used. In general, permanent magnets can retain their magnetism for many years or even decades if they are not subjected to extreme conditions. However, some magnets may gradually lose their magnetism over time due to factors like exposure to high temperatures or physical damage.
Can magnetism field work?
magnetism works by the type of metal used to pull other type metal to it.
What are the magical properties that people used to attach to lodestones?
Magnetism, people believed it was magical because they had no understanding of the forces of magnetism.
What is name commonly used for moving charge?
magnetism
Which of these is not a way by which objects can become charge?
magnetism magnetism magnetism
What is an example of electricity and magnetism being used?
An electro-magnet.
Is friction used for a nail to pick up paperclips?
no it is magnetism
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 permanent magnetism?
Permanent magnetism is magnetism that is permanent. I think...
Who discovered the properties of electron magnetism?
Who were the first to discover a substance with magnetic properties
Can you produce electricity even without magnetism?
yes we can produce electricity without magnetism by using semiconductor for example photo diode is used in solar cells.
What magnet keeps its magnetism for a long time?
Neodymium magnets are known for retaining their magnetism for a long time due to their strong magnetic properties. They are commonly used in various applications where long-term magnetism is important, such as in electric motors and generators.
How does magnetism and electricity work together?
When current flows in a conductor there is a magnetic field formed around the conductor. This magnetic field can be used to make an electric magnet (like the ones used at junkyards), motors also use magnetism to operate, and many switches (solenoid, motor starters, and relay switches) use magnetism to open or close.
