    Explaining paramagnetism, diamagnetism, and ferromagnetism

    I have a short paper to write this weekend and my physics book doesn't do a very good job of explaining paramagnetism, diamagnetism, and ferromagnetism. Anyone know a good website that gives similarities and differences among those 3 types of magnetism? Thank you.

    What is the electric flux through the hemispherical surface?

    A uniform field E is parallel to the axis of a hollow hemisphere of radius R. a) What is the electric flux through the hemispherical surface? b) What is the result if E is instead perpendicular to the axis? Here is what I've interpretted so far. If the field is parallel to the surface, then...

    How Can You Solve Coulomb's Law Problems with Electric Charges and Forces?

    I have a couple of Coulomb's Law problems. 1) A charge of 6.00 mC is placed at each corner of a square 0.100 m on each side. Determine the magnitude and direction of the force on each charge. 2) Two charges, -Q and -3Q (subscript 0 at the end of each Q),are a distance L apart. There...
