上年考完DSE

Physics考得還好

今年又有讀相關嘅科目
同埋做私補Physics
自己本身鍾意做Physics

如果有唔識嘅問題，歡迎upload上嚟問下我

DSE加油

歡迎隨便問

問幾多都冇問題

唔係R私補，都唔係補習社

A )Current increase means B field increase
By Lens law Q should induce a opposite direction B field. B field opposite means current also opposite
A correct

B) From t1 to t2 I decrease means B field decrease
By Lens law Q should induce a same direction B field.
B correct

C & D 問得有啲差冇講明係咩force
不過D一定錯
因為t2 change in I 最大

左手係induced voltage/currect
右手係induced force
力距焦距係啲乜嘢
我讀英文phy唔好意思

佢嘅意思係U經過好多次decay之後會變成Pb
因為中間嘅過程好多所以
將佢簡化做一個step
題目話嘅2比3即係淨番60%嘅U
