A toroid of mean radius 25cm and circular cross-section of radius 2cm is wound with a superconducting wire of length 1000m that carries a current of 400A. 1. What is the number of turns in the coil?
2. What is the magnetic field at the mean radius?
3. Assuming B is constant over the area of the coil, calculate the magnetic energy density and the total energy stored in the toroid
4. Calculate the self inductance of the toroid

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.

the following is queen elizabeth’s purposes:

- to encourage the parliament that the technique of picking successors to the seat based merely on birthright needs to be reviewed.

- (not) to convince the parliament that her kid should not be measured as a likely choice for heir to the english power.

- to persuade the parliament that merely since she has a child does not assure that the kid will be a capable leader.

- to sway the parliament how shattering it could be if they proceeded discourteously concerning her or her child.
