Find Bz at the center of each coil and compare it to the value at the midpoint (point P) between the coils.
I tried doing this one the best that I can and don't know what I am missing from my equation since I tried accounting for the oppisite current making it's own opisite magnetic field but I don't know how else I can put the equation together. Can you help me figure out what I am missing?
Pls help me with the following question and make sure it's 100% correct One solenoid is centered inside another. The outer one has a length of 53.0 cmcm and contains 6650 coils, while the coaxial inner solenoid is 3.00 cmcm long and 0.140 cmcm in diameter and contains 15.0 coils. The current in the outer solenoid is changing at 36.0 A/sA/s . For related problem-solving tips and strategies, you may want to view a Video Tutor Solution of The Tesla coil. Part A. What is the mutual inductance of these solenoids? Express your answer in microhenrys. Part B. Find the emf induced in the inner solenoid. Express your answer in volts.

Review. Alter removing one string while restringing his acoustic guitar, a student is distracted by a video game. His experimentalist roommate notices his inattention and attaches one end of the string, of linear density = 3.00 10-3 kg/m. to a rigid support. The other end passes over a pulley, a distance = 64.0 cm from the fixed end, and an object of mass m = 27.2 kg is attached to the hanging end of the string. The roommate places a magnet across the string as shown in Figure P31.35. The magnet does not touch the string, but produces a uniform field of 4.50 mT over a 2.00-cm length of the string and negligible field elsewhere. Strumming the string sets it vibrating vertically at its fundamental (lowest) frequency. The section of the string in the magnetic field moves perpendicular to the field with a uniform amplitude of 1.50 cm. Find (a) the frequency and (b) the amplitude of the emf induced between the ends of the string.
