Solenoids are cylindrical coils of wire that create an internal magnetic field when carrying an electric current - see section 12.1 of the textbook. A solenoid 86.0 cm long has a radius of 3.00 cm and a winding of 1900 turns; it carries a current of 3.60 A. (a) Calculate the magnitude of the magnetic field inside the solenoid in mT. (b) Calculate the magnetic field outside the solenoid in T. (We can treat this as an ideal solenoid, since...
Magnetic Field inside a Very Long Solenoid Learning Goal: To apply Ampère's law to find the magnetic field inside an infinite solenoid. In this problem we will apply Ampère's law, written ?B? (r? )?dl? =?0Iencl, to calculate the magnetic field inside a very long solenoid (only a relatively short segment of the solenoid is shown in the pictures). The segment of the solenoid shown in (Figure 1) has length L, diameter D, and n turns per unit length with each...
Induction and Faraday's Law In the long solenoid shown in the figure, the number of turns per unit length is n_1 = 220 turns/cm. At the center of this solenoid there is a shorter solenoid made of N_2 = 130 turns closely spaced. The diameter of the smaller solenoid is d_2 = 2.1cm, and its axis coincides with the axis of the longer solenoid. The current in the first solenoid grows linearly by an amount delta I = 1.5 A...
