向きはどのようにして考えるのですか？？

EX r〔m〕 離れた十分長い2本の直線導線に電流 I [A], I 〔A〕 が逆向きに流れている。 A, B それぞ れの長さ 〔m〕 の部分が受ける力の大きさ 〔N〕 お よび向きを求めよ。 透磁率をμ [N/A²] とする。 In 2πr 解 BがAの位置につくる磁場の強さは HB= μI, I ₂ l Aが受ける力は F^=I・μHB・l= 2πr μI, I₂1 I₁ 2πr FB=IzμHA・l= 2πr FA = FB となるのは作用・反作用からも理解できる。 同様にH= ⅣV 電流と磁場 I₁ A A FAX HB B B In 93 HA I₂ FB

A点はなぜ2つの電流が作る磁場が同じ向きだと考えられるのですか？？

56 xy平面上, x = 0, 4α の位置に2I,3Iの直 線電流が図の向きに流れている。 A点, B点で の磁場の強さと向きを求めよ。 また, B点を中 心として半径aの円形電流をxy平面内で流し, Bでの磁場を0とするにはどちら向きに流せば よいか。 その強さ I'はいくらか。 87 A 2a 4a 31 B 6a x

There are almost no earthquakes in your country, right? No, I haven't experienced one in the U.K. Can you tell me what to do? Sure. The first priority is your safety. Hide under a desk or table to protect your head. Stay there until the earthquake stops. Then be prepared to move to a safer place. I'm sure we'll do some simulations in the evacuation drill held at school next Monday. We'll learn there what's important to do during an earthquake. Wow! That sounds great. I'm looking ( 1) the drill now. Maybe we can get "Moriyama-ku Evacuation Map" after the drill. It shows you (in, where, should, you, a disaster, go ). Jane: Risa: Oh, I'm glad to know that. You should make an emergency kit, too. Our family has made one each and put them near their bed. I see. Can you tell me how I should make it? Well, I'll send you an email later then.
