Is mri electromagnet?
Yes
What is the name of a machine in which the magnetic field is provided by an electromagnet?
MRI machine
What are the electromagnet uses?
Electromagnetics are used to create (strong) magnetic fields. This has many applications, from MRI to see brain activity to determining molecular properties to making frogs fly.
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 :)
Why are cryogens used in mri?
To keep the magnet cool. MRI machines need to generate a very strong magnetic field. They do this using superconducting electromagnet- basically a large coil of wire with a large current passing through it. The magnet must be kept very cold, almost at absolute zero, or it will not superconduct.
What are not likely to be affected by a magnet?
Organic materials such as plants and animals are almost unaffected by a magnet. In fact, one of the most powerful magnets you are ever likely to see is the electromagnet of a Magnetic Resonance Imaging (MRI) machine.
Do you say an MRI or a MRI?
an MRI
Do you say a MRI or an MRI?

Why liquid helium is used in body scanners?
The "body scanners" that use it are Magnetic Resonance Imaging, or MRI, machines. (The scanners at airports are akin to radar sets, and don't use liquid helium.) MRI machines contain a very large electromagnet. To keep the thing from requiring its own power plant, an MRI magnet is wound with superconducting wire - wire with, effectively, no resistance. Superconducting wire must be kept at the temperature of liquid helium if you want it to superconduct.
Which is better a permanent magnet or an electromagnet?
electromagnet
Strong temporary magnet formed when a current is passed through a coil of wire?
A magnetic field.
