Discuss the fact that only ferromagnetic materials (materials containing iron, cobalt, nickel and some rare earth elements) exhibit magnetic attraction. Most metals (aluminum, copper, gold, lead, silver, zinc, etc.) are NOT attracted to a magnet.

Are coins magnetic?
A common US five-cent piece is called a “nickel”, but it is only 25 percent nickel, with the balance being copper. Therefore, it is not magnetic. Of all US coins ever issued for circulation, only 1943 Steel Cents are considered magnetic. Many Canadian coins, especially those made in 1968 or later, are magnetic.
Are some metals more magnetic than others?
Some metals contain certain properties that make them more magnetic than others. One metal that is highly magnetic is iron. … There are three main types of magnetic metals: ferromagnetic, paramagnetic, and diamagnetic.
Do magnets stick to brass?
In their natural states, metals such as brass, copper, gold, and silver will not attract magnets. This is because they are weak metals to start with.
Is silver magnetic?
“Silver is not noticeably magnetic, and exhibits only weak magnetic effects unlike iron, nickel, cobalt, and the like,” says Martin.
Which set of metals are highly magnetic by nature?
Ferromagnetic metals are strongly attracted by a magnetic force. The common ferromagnetic metals include iron, nickel, cobalt, gadolinium, dysprosium and alloys such as steel that also contain specific ferromagnetic metals such as iron or nickel. Ferromagnetic metals are commonly used to make permanent magnets.
Does magnet attract mercury?
At room temperature, the element mercury is not very magnetic at all. It has a very small, negative magnetic susceptibility, meaning that when you put mercury in a magnetic field, it magnetizes just a little tiny bit in the opposite direction. We say that mercury is a weakly diamagnetic substance at room temperature.
