Solution

$$Induction$$ : "Charging an uncharged conductor by bringing a charged conductor near it without touching is called $$induction$$ .
Place uncharged conductor $$ B $$ near +vely charged conductor $$ A $$ nearer end of $$ B $$ has -vely charged electrons attracted towards +vely protons remain on farther end of $$ B $$. Hence, nearer end of $$ B $$ is charged oppositely i.e. negative. We can test it by pith ball electroscope. On removing charged body $$ A $$ away from $$ B $$, The body $$ B $$ becomes neutral due to protons and electron in $$ B $$ are equal and have opposite charge.
