Permanent Magnets
Permanent magnets are those we are most familiar with, such as the magnets hanging onto our refrigerator doors. They are permanent in the sense that once they are magnetized, they retain a level of magnetism. As we will see, different types of permanent magnets have different characteristics or properties concerning how easily they can be demagnetized, how strong they can be, how their strength varies with temperature, and so on.
Temporary Magnets
Temporary magnets are those which act like a permanent magnet when they are within a strong magnetic field, but lose their magnetism when the magnetic field disappears. Examples would be paperclips and nails and other soft iron items.
Electromagnets
An electromagnet is a tightly wound helical coil of wire, usually with an iron core, which acts like a permanent magnet when current is flowing in the wire. The strength and polarity of the magnetic field created by the electromagnet are adjustable by changing the magnitude of the current flowing through the wire and by changing the direction of the current flow.
What else can I help you with?
What kinds of magnets are there?
Both artificial and natural magnets.
How will magnets attraction of metal?
if different magnets attract metals then the attraction will be different.
How are magnets alike and How are magnets different?
My answer id they have different shapes and colors.
What kinds of metals are affected by magnets?
Primarily nickel, iron, and cobalt.
What kinds of objects are attracted by magnets?
Objects that contain iron, nickel, or cobalt are attracted by magnets. These materials are known as ferromagnetic materials.
How strong are the magnets in electronics?
Magnets of different strength are used.
Do different magnets have different strengths?
Yes, different magnets can have different strengths based on the material they are made of and how they are manufactured. For example, neodymium magnets are known to be one of the strongest types of magnets available, while ceramic magnets are typically less powerful. The strength of a magnet is often measured in terms of its magnetic field or magnetic flux density.
Do different magnets have different magnetic fields?
yes
Can different magnets attract heavier objects?
Bigger magnets are used for heavier objects.
What is the Industrial Magnets?
Industrial strength magnets are used widely for lifting, work holders,and chucks.
How many types of magnets are there?
none
Does magnets attract other kinds of material?
If the other material is magnetized, then yes.
