You can test if a material is nickel by using a nickel spot test kit or by performing a nickel chloride test. Another method is to conduct an X-ray fluorescence (XRF) analysis of the material to determine its elemental composition.
The flame test for nickel produces a blue-green color flame.
Some coins, such as the U.S. penny and nickel, are magnetic due to their composition. You can test their magnetic properties by using a magnet to see if the coin is attracted to it. If the coin sticks to the magnet, it is magnetic.
Actually it isn't either, nickel is an element. Look on the periodic table and you will see this, its symbol is Ni.
To determine if your earrings contain nickel, you can perform a simple test using a nickel testing kit available at many jewelry stores. These kits typically involve applying a drop of testing solution to a small area of the earring and observing any color changes that indicate the presence of nickel. Alternatively, you can consult the product information or contact the manufacturer to inquire about the materials used in the earrings. It's important to test for nickel if you have a known allergy to avoid any potential skin reactions.
A quick test to determine what is in a sample of a meteorite (or anything else, for that matter) is to run that sample through a mass spectrometer. Mass spectrometry (MS) will tell you whether nickel is among the constituent elements in that sample you just put through the machine. Use the links below to learn more.

One good way to tell is to use a nickel test kit. This is practical when you want to test an earring which you've already purchased. If you are purchasing a new earring, look for "guaranteed nickel-free" or "hypoallergenic" or "100% nickel-free". Jewelry marked with one of these will have no nickel or very little nickel and are less likely to irritate.
Some coins, such as the U.S. penny and nickel, are magnetic due to their composition. You can test their magnetic properties by using a magnet to see if the coin is attracted to it. If the coin sticks to the magnet, it is magnetic.

It would appear so. If you see black lines after you rub a nickel on your skin, you just might be anemic. Of course, if you rub a really dirty nickel on your skin you might get a false reading. Best see a doctor.

Oh yeah, there's nickel in oatmeal, buckwheat, most nuts, and legumes. I had a hair test done and was shocked by how much nickel I had. After cutting back on nickel-rich foods for 6 months, my hair nickel levels returned to acceptable levels. Your mileage may vary.
This coin is commonly called either a buffalo nickel or an Indian head nickel but not a "buffalo head nickel" - after all, it shows the whole buffalo! Please see the question "What is the value of a 1927 US nickel?" for more information.
