What is true about permanent magnets?
Permanent magnets have their own magnetic field that does not require external electrical current to maintain. They can attract or repel other magnetic materials without losing their magnetic properties. Common materials used for permanent magnets include iron, nickel, and cobalt.
How strong are neodymium magnets compared to other types of magnets?
Neodymium magnets are the strongest type of permanent magnets available, with a much higher magnetic strength compared to other types of magnets like ceramic or alnico magnets.
How do perpetual motion machines using magnets work?
Perpetual motion machines using magnets work by harnessing the repelling force between magnets to create continuous motion without the need for an external power source. The magnets are arranged in a way that allows them to repel each other, causing the machine to move in a continuous cycle. However, it is important to note that true perpetual motion machines are not possible due to the laws of thermodynamics.
Can magnets kill you?
No, magnets cannot kill you.
Examples of permanent magnets?
Some examples of permanent magnets include neodymium magnets, samarium cobalt magnets, and ceramic (ferrite) magnets. These magnets retain their magnetism without the need for an external magnetic field.
Is it true that magnets can attract iron?
Yes, it is.
What is true for both magnets and charges?
5
Is it true that electric current can be generated with magnets?
Electromagnetism.
Which of the following is true of permanent magnets?
They are difficult to magnetize,
Is it true or false magnet usually attract the metal iron tin cobalt?
True. Magnets typically attract materials that are magnetic, such as iron, tin, and cobalt.
If your dealing with magnets is it true that poles repel and unlike poles attract?
Yes, u got it right
What is true about permanent magnets?
Permanent magnets have their own magnetic field that does not require external electrical current to maintain. They can attract or repel other magnetic materials without losing their magnetic properties. Common materials used for permanent magnets include iron, nickel, and cobalt.
What are some names of small magnets?
Refrigerator magnets, car magnets, neodymium magnets are names of small magnets.
What is a true statement about the magnetic field between two magnets?
The south pole of one magnet is attracted to the north pole of the other magnet.
What is true for magnets but not for charges?
Magnets have north and south poles, whereas charges do not have distinct poles. Additionally, magnets can attract or repel each other based on their alignment, while charges can only attract each other. Finally, magnets can retain their magnetism even when not in contact with another magnet, whereas charges require contact to interact.
Is it true that other than metal nothing is attracted to magnets?
No. Electric current is also attracted to magnets. To see this, hold a magnet near the screen of a TV set with a CRT (not an LCD or plasma TV), and move it around.
Did christian oersted discover that electricity and magnets produce each other?
♂True...!!▬♂•♫♣ yes
