Study Notes
Magnetic Fields and Materials
- The magnetic field aspect of electromagnetism is responsible for most of the effects of magnetism encountered in everyday life.
Materials and Magnetism
- Ferromagnetic materials, such as iron, nickel, and cobalt, are strongly attracted by magnetic fields and can be magnetized to become permanent magnets.
- Paramagnetic materials, such as aluminum, oxygen, and potassium, have a more complex relationship with a magnetic field, showing neither strong attraction nor repulsion.
- Diamagnetic materials, such as copper, silver, and gold, are weakly attracted to an applied magnetic field.
Sources of Magnetic Fields
- Electric currents give rise to a magnetic field, making it one of the aspects of electromagnetism.
