[題目] 電磁學的問題
題目
A 2.4 m long solenoid is 15.0 cm in diameter and consists of 2500 turns of
wire. The current in the solenoid is increasing at the rate of 1.0 kA/s
問題
Find the current in a wire loop with diameter 7.50 cm and resistance
9.0 歐母, lying inside the solenoid in a plane perpendicular to the solenoid
axis.
我不太了解他說的perpendicular to the solenoid
到底是朝向哪個方向 感覺好抽象
可不可以請問一下這題從哪個角度切入會比較好處理
感激
