なぜ答えは③になるのでしょうか

図1に示すように、磁束密度の大きさが B 〔T] でy軸の正の向きを向いた一様 な磁場 (磁界) 中で, 細い導線でできた長方形の一巻きコイル ABCD が回転する。 辺AB と辺 CD の長さはα 〔m〕 であり,辺BCと辺DAの長さは6〔m〕 である。 辺 AB, BC, CD の電気抵抗は無視できるが, 辺 DAの電気抵抗は R [Q] である。 点Aは座標原点にある。 コイルは軸にある辺AD を軸にして,軸の正の側か ら見て反時計回りに一定の角速度w 〔rad/s] で回転している。 一巻きコイルの自 己インダクタンスは無視できる。 必要であれば以下の公式を用いてもよい。 sin (a ±3 = sin a cos β ± cosa sin 3 cos(a±β)= cos a cos β 干 sin a sin β Z (複号同順) 図1のように, 軸の正の向きと辺ABのなす角が0 〔rad〕 のとき, 辺BCの速度 ア である。 辺BCの中にある電荷-e [C] (ただ の成分 [m/s] はv= 0-0のとき、 le > 0) を持つ自由電子の速度のæ成分もと同じとすれば, 0<0く 電子は イ のローレンツ力を受ける。 これによって, 閉じている一巻きコ イル ABCD には誘導電流が流れる。 2 これを,コイルを貫く磁束が時間的に変化するという見方で見てみよう。 コイル の面と常に垂直でコイルとともに回転する矢印Nを図1のようにとる。 コイルの面 を矢印Nの向きに磁束線が貫く場合, コイルを貫く磁束は正, 逆向きに貫く場合 πT を負とする。 0 の範囲がー <0 の場合,磁束線はコイルを矢印Nの向きに買 2 2 いており, コイルを貫く磁束 (0) 〔Wb] は ウである。ファラデーの電磁誘
