An MRI (Magnetic Resonance Imaging) machine primarily uses a strong, superconducting magnet to generate a powerful and stable magnetic field. While the superconducting magnet itself is not a permanent magnet, it can maintain its magnetic field without continuous power once it is cooled to a superconducting state. However, MRI machines also utilize permanent magnets in some designs, especially in lower-field or portable MRI systems. Therefore, while the main magnet in most MRI machines is not permanent, some components may include permanent magnets.
What else can I help you with?
Match the object with its characteristic a mri permanent magnet b compass electromagnet c moon not magnetic?
ill give u the answer since i use wiki answers myself for tests and stuff *guilty* :)A mri is a electromagnetB compass is a permanent magnetC the moon is not magneticA.S apex :)
Will a MRI work without a magnet?
No. Put simply, an MRI scanner utilised radio waves and a magnetic field. Without a magnet, there is no magnetic resonance imaging (MRI).
Is the magnet in a compass a permanent magnet or electronic?
A. Compasses typically use a permanent magnet.
Is a needle in a compass a permanent magnet?
Yes, it is a permanent magnet.
Is magnetite a temporary magnet?
No, it's a permanent magnet. It consists of an iron oxide, and iron is a permanent magnet.
Can you have an MRI with a steel plate in your head?
No u can't. An MRI is done by a giant magnet.
Is the magnet in a compass a permanent magnetic or an electromagnet?
PermanentThere is no source of current in a compass, therefore the magnet is a permanent magnet.
What can a permanent magnet effect?
A permanent magnet can attract or repel other magnets, and can induce electric currents in conductive materials. It is commonly used in various applications such as electric motors, generators, and magnetic resonance imaging (MRI) machines.
How can a magnet be temporarily magnetized when attached to a permanent magnet?
When a magnet is attached to a permanent magnet, it can become temporarily magnetized by aligning its magnetic domains with the strong magnetic field of the permanent magnet. This alignment causes the magnet to exhibit magnetic properties for a short period of time.
How much stronger is a MRI magnet compared to refrigerator magnet?
20000
Is the magnet in a compass a permanent or electromagnet?
The magnet in a compass is a permanent magnet. It retains its magnetism without the need for an external electrical current.
Is a permanent magnet called a hard magnet or a electromagnet?
Perminant magnet
