The core of a long solenoid with 1000 turns/m and a current of 0. 5 A is filled with an unknown material. It is found that the magnetic field along the axis of the solenoid increases by 0.0017%. What is the magnetic susceptibility of the unknown material? A)1.7 × 10^-5 B)3.4 × 10^-5 C)0.0048 D)-3.4 × 10^-5 E)0.0021

Question

Quizplus · Accepted Answer

The increase in the magnetic field is due to the material's magnetic susceptibility. The percentage increase is 0.0017%, which corresponds to a susceptibility of 1.7 × 10^-5.
