A tightly wound solenoid 15 cm long has 350 turns and carries a current of 3.0 A.If you ignore end effects,you will find that the value of  at the center of the solenoid when there is no core is approximately

Quizplus · Accepted Answer

The magnetic field inside a solenoid with no core can be approximated using the equation:

B = μ0 * N * I / L,

where μ0 is the vacuum permeability (4π * 10^-7 T*m/A), N is the number of turns, I is the current, and L is the length of the solenoid.

Substituting the given values, we get:

B = (4π * 10^-7) * 350 * 3 / 0.15 = 8.8 mT

Therefore, the best choice is (D) 8.8 mT.
