no, only iron, cobalt, nickel and their alloys are magnetic.
They may contain naturally occurring magnetic minerals.
Yes, nickel can be magnetized.
No, lead cannot be magnetized.
No, copper is not naturally magnetized.
The not magnetized rod will be attracted by both of the magnetized rods.
Yes, if a nail is made of steel, it will will not be magnetized unless it is magnetized by a magnet by being hit.
As rocks cool past the curie point, they tend to become magnetized in the direction that the earths field is point at that time. The earths magnetic field has reversed many times in the past. The mid ocean ridge is a place where the plates are spreading apart and new hot material is welling up. This makes stripes of rocks that are magnetized in alternating directions.
These boundaries are called magnetic anomalies, where the Earth's magnetic field has shifted relative to the seafloor rocks. These anomalies are used to study the history of plate tectonics and Earth's magnetic field reversals.
Iron ore typically appears as reddish-brown rocks or dark, metallic ores that can be magnetized. Lodestone, a naturally magnetized form of magnetite, appears as dark, irregularly shaped stones with magnetic properties. Both can vary in appearance depending on their mineral composition and location.
The most common mineral that can be magnetized is magnetite.
No, copper cannot be magnetized because it is not a ferromagnetic material.
Domains in magnetized materials are all aligned in one direction - those in un-magnetized objects are arranged randomly.
