solenoid of length 2.00 cm and radius 0.750 cm has 49 turns. If the wire of the solenoid has 1.95 amps of current, what is the nagnitude of the magnetic field inside the solenoid? nagnitude of the magnetic field: gnoring the weak magnetic field outside the solenoid, find the magnetic energy density inside the solenoid. nagnetic energy density: J/m3 Vhat is the total magnetic energy inside the solenoid? otal magnetic energy: J

A solenoid 2.5 cm in diameter and 30 cm in length has 2400 turns and carries a current of 2.0 A. A)Calculate the magnetic flux through the circular cross-sectional area of the solenoid.   Hint: Assume this is a very long solenoid and use the simplified magnetic field formula for an infinite solenoid.

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.
