3 cards from this section. Quick, good the night before a test.
Define magnetisation and its units.
Think about what magnetisation represents in terms of magnetic moment and volume.
What does magnetic intensity (H) represent?
Remember it helps understand the external effects of magnetism.
What does magnetisation quantify?
Look at how we measure it in different materials.
True or False: Magnetic intensity includes the effects of the material's magnetisation.
Think about what H represents in the equations.
A material has a magnetic moment of 2 A·m² and occupies a volume of 0.05 m³. Calculate its magnetisation.
Recall the formula for magnetisation.
If a solenoid with a core is producing a magnetic field of 0.5 T and has a magnetisation of 200 A/m, what is the magnetic intensity inside it?
Consider the values of μ₀ and how they relate in the formula.
