Answer: magnet attract objects made of iron and some others metal.
Which object will not be attracted to the magnet?
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.
How does a magnet help you in picking the needles and pins easily?
A magnet attracts the steel pin. When the pin touches the magnet it can’t attract it any closer and it sticks to the magnet. When things are being glued they have to come into contact. However, a magnet will attract a pin from a distance.
Which of the following objects can be separated by a magnet?
Mixtures containing substances that are attracted by magnets can be separated using a magnet. We can separate iron from a mixture of sand and iron, as only the iron is attracted to the magnet.
Separating Mixtures: Using Magnets.

What objects attract magnets?
Iron, cobalt and nickel, as well as alloys composed of these ferromagnetic metals, are strongly attracted to magnets. Other ferromagnetic metals include gadolinium, neodymium and samarium. Paramagnetic metals are weakly attracted to magnets, and include platinum, tungsten, aluminum and magnesium.
Which object will not be attracted to?
Those materials which are not attracted by a magnet are called non- magnetic materials. All the substances other than iron, nickel, and Cobalt are non-magnetic substances for example plastic, rubber, water, etc are nonmagnetic materials.
How do you magnetise a needle?
Rub the magnet against the sewing needle at least five times. (If you are using a weaker magnet, such as a flat refrigerator magnet, rub the needle at least a dozen times.) Always rub the magnet in the same direction against the needle. Your needle should now be magnetized.
Can you make a compass?
It’s composed of a magnetized needle that aligns itself with the earth’s magnetic field to point north. If you find yourself lost without a compass, you can easily make your own using a piece of magnetized metal and a bowl of water .
Why do magnets not attract paper?
In most substances, equal numbers of electrons spin in opposite directions, which cancels out their magnetism. That is why materials such as cloth or paper are said to be weakly magnetic. In substances such as iron, cobalt, and nickel, most of the electrons spin in the same direction.
What is nickel attracted to?
Magnetism. Nickel is one of only four metals that are ferromagnetic, meaning they are attracted to magnets and are magnetic themselves. The others are iron, cobalt and gadolinium.
Are marbles attracted to magnets?
Magnetic force is traveling through the paper clips to hold them together. *All the surfaces that attract the marbles contain iron. Other metals such as aluminum will not attract them.
What do you called the object that has the ability to attract the other substance?
Magnets are objects, which can attract, or pull, on some metals, like iron and steel. … Magnets can also attract each other, but only if they face in opposite directions. A magnet has two ends called poles; one end is the north pole and the other is the south pole.
Are paper clips magnetic?
Paperclips are not naturally magnetic, so, on their own, they will not stick together to form a chain. However, by using a magnet the paperclips can become temporarily magnetized. The steel in a paper clip can be easily magnetized but will lose this magnetism quickly.
Is gold magnetic?
Gold had long been considered a non-magnetic metal. But researchers recently discovered that gold can in fact be magnetized by applying heat. Gold had long been considered a non-magnetic metal. But researchers at Tohoku University recently discovered that gold can in fact be magnetized by applying heat.
Is Brass attracted to magnets?
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.
