Electromagnets offer large magnetic fields up to 2.6 T, large spaces for uniform magnetic field, and different field orientations.
Special electromagnets include:
Protruding Pole Electromagnets
Helmholtz Coils generate a uniform magnetic field over a large open space. The magnetic field is typically below 500 Gauss (0.05 T).
Special Helmholtz Coils Include:
1D, 2D, and 3D Helmholtz Coils
Solenoids create uniform magnetic fields inside the coil up to about 2 kG (0.2 T). They can also be used as a sensing coil to detect magnetic fields or magnetic induction.
Special solenoids include:
Special arrangements of permanent magnets are used to generate magnetic fields, featuring small sizes and large magnetic fields.
Special permanent magnets include:
Permanent Magnets for fixed magnetic fields up to 1.1 T
Permanent Magnets for magnetic field calibration from 0.1 to 1.1 T
