What's the question?

Answer 4

Answer 5

I believe its strongest near the charge itself. As it gets far away from the charge it gets a bit weaker.

Answer 6

You could say the field is strongest at the charge or really near it, since the field becomes weaker as the distance from that field(r) increases.

Answer 7

Answer 9

@shiraz14 do you know the second one i just posted here?

Answer 10

For the second question, the north magnetic pole of the compass will point towards the north magnetic pole of the Earth which is in fact the South pole of the Earth's magnetic field.

Answer 11

You can see this from the field lines which terminate at the "North" magnetic pole (aka the South pole of the Earth's magnetic field).
