The magnet dimensions are about 6x6x12mm. If a 12 mm long solenoid were constructed with 100 turns - each turn having a 36mm^2 cross sectional area, how much current would it have to carry to have the dipole strength of your magnet?

It is reasonable to assume that the bulk modulus of blood is about the same as that of water (2.2 gpa). as one goes deeper and deeper in the ocean, the pressure increases by 10000 pa for every meter below the surface. if a diver goes down 80.0 m in the ocean, by how much does each cubic centimeter of her blood change in volume? give the answer in cubic centimeters (actually one cubic centimeter equals one milliliter).
