5 Questions
Which one of these is the cause of magnetism?
One electron in each orbital
What is the risk of having ferrous objects in the MR environment?
They may be attracted to the MRI unit
What is the cause of paramagnetism?
One electron in each orbital
What is the cause of diamagnetism?
All orbitals containing two electrons
Which one of these is an example of a diamagnetic substance?
Copper
Study Notes
- Magnetism is created by the principles defined by Pauli’s Exclusion Principle.
- Ferromagnetism is created when crystal-like structures within a substance contained atoms with one electron in its orbital.
- When only one electron is found within an orbital, a charge is place on the atom.
- Ferrous objects are not allowed in the MR environment due to the risk that they may be attracted towards the gantry of the MRI unit.
- Paramagnetism is created when atoms in a substance contained one electron in its orbital.
- Diamagnetism is created when atoms in a substance contained no electrons in its orbital.
- Diamagnetic substances have no net charge and are repelled by an external magnetic field.
- Copper, gold, and silver are examples of diamagnetic substances.
- Diamagnetic substances are created when all the orbitals within an atom contain two electrons.
- When placed in an external magnetic field, diamagnetic substances are repelled.
