A 0100-M Long Solenoid Has a Radius of 0

Question 39

Multiple Choice

A 0.100-m long solenoid has a radius of 0.050 m and 1.50 × 104 turns. The current in the solenoid changes at a rate of 6.0 A/s. A conducting loop of radius 0.0200 m is placed at the center of the solenoid with its axis the same as that of the solenoid as shown. A 0.100-m long solenoid has a radius of 0.050 m and 1.50 × 10<sup>4</sup> turns. The current in the solenoid changes at a rate of 6.0 A/s. A conducting loop of radius 0.0200 m is placed at the center of the solenoid with its axis the same as that of the solenoid as shown.   -What is the magnetic flux through the small loop when the current through the solenoid is 2.50 A? A) 2.95 × 10<sup>-</sup><sup>2</sup> Wb B) 7.28 × 10<sup>-</sup><sup>2</sup> Wb C) 2.95 × 10<sup>-</sup><sup>4</sup> Wb D) 4.38 × 10<sup>-</sup><sup>4</sup> Wb E) 5.92 × 10<sup>-</sup><sup>4</sup> Wb
