Mr. Green and Mrs. Green have a son, Tom. They love him very much. Tom is only three years old. He likes asking questions.
One day Mr. Green is sitting in a chair. He is reading a book and he has a banana in his hand. He likes to eat one while(当…… 时候)reading. Tom comes in. He asks Mr. Green, “Daddy, what’s that?” Mr. Green is interested in(对……感兴趣) the book. He doesn’t hear Tom. Tom shakes(摇动) his father’s leg and asks again, “What’s this? Tell me!” “A leg!” says Mr. Green.
Tom goes out and says to Mrs. Green, “Mum, I want to eat a leg.”

(1)在图20中,甲为某磁极附近磁感线的方向和分布的示意图,由图可知,该磁极为 ▲ 极,若在l处放置一个小磁针,当小磁针静止时,其指向应是图乙中的 ▲ .
(2)磁敏电阻阻值的大小随磁场的强弱变化而变,图丁是某磁敏电阻R的阻值随磁感应强度B变化的图象,据图线可知,磁敏电阻的阻值随磁感应强度B的增大而▲ .图线没有过坐标原点,说明 ▲ .
(3)王强设计了一个可以测量该磁敏电阻R的电路如图丙所示,(其中磁敏电阻所处的磁场未画出).将该磁敏电阻R放置在磁场中的位置某处,测出电阻后,利用R—B特性曲线可以读出相应的磁感应强度.
①在图甲磁场中1处,测得的数据如图20表中所示,则该磁敏电阻的测量值为 ▲ Ω.
②根据该磁敏电阻的R-B特性曲线可知,1处的磁感应强度为 ▲ T.
③在实验过程中,仅将磁敏电阻从1处移至2处,其它条件不变,那么电流表的示数
▲ (填“增大”、“减小”或“不变”).
④依据上述方法获得的磁感应强度B的测量值与该点实际值存在不小的误差,为尽可能准确反映空间某点磁场的强弱,你认为在选择磁敏电阻时应注意什么问题? 查看习题详情和答案>>
