Course Description
Electromagnets have a wide variety of uses in all areas of industry. Additionally, the ability to temporarily create an electromagnet from a part made of ferromagnetic metals is key to performing magnetic particle examinations.
By the end of this course, you will be able to
• Define magnetic field strength
• Understand the unit of measure for magnetic field strength
• Differentiate between B and H fields
• Understand the effect of a material's permeability on the B field
• Define relative permeability
• Understand why a ferromagnetic metal has varying permeability
• Define coercive force
• Understand the relationship among residual magnetism, retentivity, and saturation
• Understand the relationship of magnetic field strength and magnetic flux density fields as represented by a hysteresis loop
• Understand the effects the properties of a ferromagnetic metal have on the hysteresis loop
