Nov 21, 2008 · I have a question about AC magnetic field, wondering if you can help me understand this. For a DC solenoid coil, We can say Magnetic field H=N*i/L (simplest form) For an AC input, H=N*isin(wt)/L ; H(rms) = N*i/L (i is RMS value) As long as the current i-rms is kept constant, the solenoid must produce the same magnetic field at any frequency. the magnetic field and loop current are both zero. Subsequently, the current increases according to I = bt 2, where b is a constant with the units A /s 2. Find an expression for the magnetic field strength as a function of time. Solution The induced current and the derivative of the magnetic field strength are related as in the previous problem ... 4) A magnetic field of 37.2 T has been achieved at the MIT Francis Bitter National Magnetic Laboratory.

Jun 25, 2016 · Electromagnetism 77. 75. Magnetic Field of a Solenoid The magnetic field is stronger in the region of the solenoid. The field lines in this region are parallel to each other showing that the field has the same strength along most of the inner part of the solenoid. Electromagnetism 78. perpendicular to the applied magnetic field (See Fig. 10) and [9] . Fig. 9. Cold diodes test setup: current parallel to the field (left), and perpendicular (right). Fig. 10. Measured cold diodes opening voltages at different external fields. In the MuCool solenoid the diode current will be in general parallel to the 2 T field in this area. The form of the magnetic field from a current element in the Biot-Savart law becomes. which in this case simplifies greatly because the angle =90 ° for all points along the path and the distance to the field point is constant.
