- The superconducting magnet of an MRI scanner requires 810 A of current to create a magnetic field of 4.5 T in the center of its solenoid coil with a 0.65 m radius. If the solenoid is 1.9 m long, how many loops of wire does it have? N =In a solenoid in vacuum of length l = 10 cm with 2052 turns per meter the current creates the field B = 70 µT. What will be the value of the current if the solenoid is placed in an external uniform magnetic field Bext = 35 µT with field lines exactly opposite to the field produced by the solenoid? Assume µo = 4Tt × 10¬7 H/m and give your answer in milli-amperes (mA).When the current in a long, straight, air-filled solenoid is changing at the rate of 2000 A/s, the voltage across the solenoid is 0.600 V. The solenoid has 1200 turns and uniform cross-sectional area 25.0 mm2 . Assume that the magnetic field is uniform inside the solenoid and zero outside, so the result L =m0AN2/l applies. What is the magnitude B of the magnetic field in the interior of the solenoid when the current in the solenoid is 3.00 A?
