Can a magnet repel ferromagnetic material?
Magnets are always attracted to ferromagnetic substances like iron, cobalt, nickel and the alloys containing them (example: steel). Ferromagnetic materials not only get attracted to magnets, but they can also retain the magnetic properties after the magnet is removed.
How do you get a magnet to repel?
Every magnet has both a north and a south pole. When you place the north pole of one magnet near the south pole of another magnet, they are attracted to one another. When you place like poles of two magnets near each other (north to north or south to south), they will repel each other.
Can a magnet must be touching an object to repel it?
Magnetism can work over a distance, meaning that a magnet does not have to be touching an object to attract it or repel it. Not all metals can be magnets. Only certain metals have magnetic properties, namely iron, nickel, cobalt, and a few rare-earth metals such as neodymium.
What part of the magnet is the strongest?
pole
What is north and south pole in magnet?
A bar magnet suspended in Earth’s magnetic field orients itself in a north–south direction. The north-seeking pole of such a magnet, or any similar pole, is called a north magnetic pole. The south-seeking pole, or any pole similar to it, is called a south magnetic pole.
Is north pole of a magnet positive or negative?
The question is, which is which? When magnets are used in magnetic therapy, the poles are often referred to as being positive or negative. Generally, the south pole is termed positive, and the north negative.
Which one of the following is an example of natural magnet?
An example of a natural magnet is the lodestone, also called magnetite. Other examples are pyrrhotite, ferrite, and columbite.
What is the difference between natural and artificial magnet?
A natural magnet is a magnet that occurs naturally in nature. Artificial magnets are magnets made by people. An example of a natural magnet is the lodestone, also called magnetite.
What is a artificial magnet?
Magnet which are made from iron in different components shape and sizes for different uses are called artificial magnet. It is a magnetized piece of iron, steel, Cobalt or nickel. These magnets are of different sizes and shapes.
What is another name for magnetite?
The chemical IUPAC name is iron(II,III) oxide and the common chemical name is ferrous-ferric oxide….

Which is better hematite or magnetite?
The mineral magnetite actually has higher iron content than the mineral hematite. However, while hematite ore generally contains large concentrations of hematite, magnetite ore generally holds low concentrations of magnetite. Magnetite ore’s magnetic properties are helpful during this process.
