The Levitron consists of a base and a top.

However, it's wise to separate this notion of a spinning particle from the quantum mechanical property we call spin.

The following two nuclear processes are used to assemble a MRI.

Permanent magnets are objects that are made up of materials that have been magnetized and can hold their own magnetic field.

properties of magnetic field lines• Using a bit of the old Pythagoras we can rewrite in terms of and So now our equation looks like this Now we want to get rid of that , so we integrate Now we know from the diagram at the start that the total charge on the disk is , so if we add up all the little bits of the total should be , so the integral is just.

Magnetic field lines denote the direction of the magnetic force at any point in space.

To understand the idea of this technology, some understanding of electromagnetic induction is required.

Everything's due to electron spin.

Note that you can put in less energy to give a rotation of less than 90 degrees, which is often used in gradient-echo sequences.
