Angle of Dip
If a non-magnetic piece of metal like copper is suspended at its center of gravity, the copper plate remains horizontally in equilibrium. If on the other hand, a magnetic needle is suspended at its center of gravity so that it is free to take up any position in the magnetic north-south plane, it m..

I dont even think my school teachers has as much knowledge as this tutors does. Tutor Vista ROCKS.........
Tutor is well courteous and patient. I look forward to working with the same tutor if possible.
We got alot done all the responses were fast the internet was kinda slow but that cant be helped this was a good tutor and they taught everything clearly. - Jenifer
Its Johnson, I have a kid studying in grade 8th, he got live help from this site and he called me to make him join it which I did. Its really helping him.
