RF Shielding actually has little to do with the magnetic field generated by an MRI Scanner. The purpose of The RF Shielding installed in an MRI exam room is to prevent radio frequency interference from entering into the MRI Scanner and causing image quality degradation.

What are the best tools for performing radio frequency identification?
The tools for performing Radio Frequency Identification (RFID) would be a two-way radio transmitter-receiver and a magnetic field that powers and reads RFID's at a short distance.
Where are the headquarters of EMI shielding?
EMI shielding is not a company but refers to the process of protecting transmission into or out of a building of electromagnetic information. It is usually coupled with RFI (radio frequency information) shielding.
What are frequency?
The frequency or rate of precession of the nuclear magnetic moment (spins) and is proportional to the magnetic field strength. Radio waves of the Larmor frequency are used to produce RF pulses. here is the link where I got this information. www.elp.manchester.ac.uk/pub_projects/2000/mmmr7gjw/glossary.htm then select the L letter

What is a radio wave's relative wavelength and frequency compared to other waves in the Electro-Magnetic Spectrum?
Radio waves are the lowest frequency (and therefore longest wavelength) waves in the electromagnetic spectrum.
What is the full form of FM?
In the radio field, FM stands for 'Frequency Modulation'.
Do magnetic fields affect X Rays?
Fixed magnetic fields, such as the field around a piece of magnetic metal or around a planet such as the earth have no effect on what is called "electromagnetic" or "wave" radiation, which includes, radio waves, microwaves, infrared, visible, and ultraviolet light, x-rays, and gamma rays (named in order of increasing energy and frequency.)
What diagnostic technique uses a combination of radio waves and a strong magnetic field to produce images?
magnetic resonance imaging
What is the use of case pin in BFW11?
BFW11 is a Radio Frequency, low noise F.E.T. The case pin should be connected to the signal ground to best guarantee a proper shielding.
What type of energy transfers information from a radio station to the radio?
RF stands for Radio Frequency, magnetic waves radiate out of the transmitting antenna and are picked up or recovered by the receiving antenna at the receiver.
Why does an electric current have a magnetic field?
A current carrying conductor, such as a metal wire, will produce a magnetic field around it because of the motion of charge within the wire itself. This motion produces or sets up a magnetic field around the wire in the form of concentric circles. This electromagnetic effect is described in physics by the Biot-Savart Law, an experimentally deduced inverse-square law. The effect is also described by Ampère's Law, which is derived from the Biot-Savart Law. This law relates magnetic field and current. Also, a magnetic field that is set up by an electrical current will produce a magnetic force. This force depends on the rate of charge transfer and the magnetic field. The force produced by a current-carrying wire depends on the length, the magnetic field, and the current, which is the charge flow per unit of time.
What imaging techniques is a noninavasive method that uses radio waves and strong magnetic field?
PET scan
