如图所示，一单匝线圈从左侧进入磁场．在此过程中，线圈的磁通量将______（选填“变大”或“变小”）若上述过程所经历的时间为0.1s，线圈中产生的感应电动势为0.2V，则线圈中的磁通量变化了______Wb．此过程______（能或不能）产生感应电流．
根据磁通量公式Φ=BS得知，单匝线圈从左侧进入磁场的过程中，线圈的磁通量变大．
根据法拉电磁感应定律E=
得，△Φ=E?△t=0.2×0.1V=0.02V．△Φ △t
由于穿过闭合线圈的磁通量增大，则线圈中能产生感应电流．
故答案为：变大，0.02，能．
Mrs. Black is sixty-nine years old. She only has a daughter named Sandra. ___小题1:__ Mrs. Black was very sad and lived in her house alone. Two years ago her daughter had a baby. The young woman was busy all the time and had no time to look after her son James. She asked her mother to live with them.
