When rocks from cooling lava harden do they have the same magnetism as Earth's magnetism?
No, because Earth's magnetism "flips" about every half million years. When rock form from the cooling lava of volcanoes, the particular magnetic pattern at the time is "frozen" into the rocks. This was evidence that the alternating pattern of the rock has been slowly spreading out as the new crust is formed.
How is magnetism created and what are two ways that it can be generated?
Magnetism is created by the alignment of magnetic domains in a material. Two ways to generate magnetism are by passing an electric current through a coil of wire (electromagnetism) or by exposing a material to a strong magnetic field (permanent magnetism).
How does copper exhibit magnetism in its properties?
Copper does not exhibit magnetism in its properties because it is not a ferromagnetic material. This means that copper does not have a strong attraction to magnets and does not retain magnetism when exposed to a magnetic field.
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 would be a good title for gravity friction magnetism?
'Gravictism'? (Formed from Gravity, Friction and Magnetism)
What atmospheric condition is formed due to the magnetism of the earth?

What determines the magnetism of rocks formed from cooling magma?
The composition of the magma and the local magnetic flux as it crossed the Curie point.
What is permanent magnetism?
Permanent magnetism is magnetism that is permanent. I think...
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.

How can you remove magnetism from springs?
Removing magnetism from something is often called degaussing. A degausser uses an alternating current to create an alternating magnetic field that "sweeps" the magnetic fields from things in which they have appeared. The degausser randomizes the magnetic domains that had formed in the metal of the springs.
Is magnetism a solid?
Magnetism is a force not a solid.
