- In modern Magnetic Resonance Imaging (MRI), the system is resistance free. The resistance-free Magnetic Resonance Imaging (MRI) is created by submerging the solenoid electromagnet into a cryogenic liquid such as liquid helium (He).eHH The temperature of liquid helium (He) is 4 Kelvin (K), which is -4,520 Fahrenheit (F). What type of magnet creates the resistance-free system?Suppose you have a long, skinny conductor that is oriented with its long axis parallel to a uniform magnetic field. Suppose also that the conductor is moving along its long axis in a straight line at constant velocity v. Despite the motion of the conductor, no motional emf is induced. Why? The magnetic field is too uniform The velocity has no component normal to the magnetic field The velocity is too low The conductor is so long and so thin that its electrical resistance is too highMagnetic flux increases from 0 to 2 Tm2 in one turn conducting loop within 0.5s. What is the induced emf in the loop? 0.5 V 2 V 0.3 V 4 V 1 V
