- or the future Electron Ion Collider (EIC) a proposed magnet for the detector is a solenoid with the following properties: B = 3 Tesla (assume uniform inside, 0 outside) Length L = 4.0 m Inner Radius R = 1.5 m Use the long thin solenoid approximation of uniform field, even though this is a short squat solenoid A). Assuming the coil has radius R = 1.5 m, what is the current density (Amp per unit length) B) Calculate the total stored energy in the magnetic field, in Joules. Given that 1 gallon of gasoline contains about 10 8 Joules of chemical energy is this a large, medium, or small amount of stored energy? C) The coil would be superconducting. If the coil were to suddenly lose it's superconductivity and the magnetic field ramped down extremely rapidly, where would the stored energy go?A large water main is 2.25 m in diameter and the average water velocity is 6.75 m/s. If there are some slight impurities in the water, it can easily become a conductor and this flow represents a small electrical current. d = 2.25 mv = 6.75 m/s Find the Hall voltage produced if the pipe runs perpendicular to the Earth’s 5.00 × 10-5 T field.Electric current is surrounded by a magnetic field.
