Why are magnets bipolar?
Magnets have two poles, a north pole and a south pole, because of the alignment of their electrons. The electrons in a magnet tend to align in the same direction, creating a magnetic field that has distinct north and south poles. This property is due to the presence of magnetic domains within the material, which align and create a bipolar magnet.
What are types of healing magnets?
Magnets have long been claimed to have biological effects though no careful objective clinical trials have ever demonstrated this. Nonetheless, there is a thriving business associated with "healing magnets." The magnets sold as healing magnets are made from the same materials as all other magnets are made from. Examples of the magnets and their use include the following. a) FLEXIBLE MAGNETIC RUBBER Flexible magnetic rubber magnets are commonly formed in sheets or strips and used for magnetic therapy in shoe insoles.. b) CERAMIC MAGNETS Ceramic magnets are most commonly used in body wraps, pads and cushions. c) NEODYMIUM MAGNETS Most commonly used in magnetic jewelry, bracelets, and individually on pain trigger or acupuncture points. d) SAMARIUM COBALT MAGNETS Most commonly used magnets in high quality jewelry where rusting is to be avoided. A very expensive magnet, very brittle, therefore labor intensive. e) HEMATITE MAGNETS Beaded magnetic hematite is very commonly used as bead magnets in high quality jewelry where bead strands are used to create beaded hematite bracelets, beaded hematite necklaces, or beaded hematite belts. With hematite the jewelry is the magnet rather than a magnetic insert into the jewelry.
Why loudspeaker cannot be used to produce ultrasonic?
because speakers doesn't create ultrasonic waves, they create sound waves
What is a sentence with ultrasonic in it?
When an object starts to move at ultrasonic speeds it will create a sonic boom.
Can ultrasonic waves create electricity?
Yes.
Why loudspeaker cannot be used to produce ultrasonic waves?
because speakers doesn't create ultrasonic waves, they create sound waves
Can two magnets create a vacuum?
No
Can an ultrasonic wave be produced by using speakers?
no Because ultrasonic sound waves are not audible and it is not possible to create that much loudness in normal speakers.
Which materials can magnets be made from?
Iron, nickel, and cobalt are used to create permanent magnets.
Do magnets make electricity?
No. Magnets create an electric feild, not electricity.However, when you spin a magnet inside a coil of wire (or you can spin the coil of wire instead), you will create an electrical current.
Why are magnets used in refregeraters door?
To create an airtight seal.
How do you power a fan with magnets?
You can power a fan by putting magnets on all the flaps that make the air then put another magnet near it to make it move and the repel of the magnets will create movement.
