Final answer:
The SI unit for magnetic field intensity is A/m (Ampere per meter), while the unit for magnetic flux density is T (tesla).
Step-by-step explanation:
The SI unit for magnetic field intensity, also known as magnetic field strength (H), is Ampere per meter (A/m). This is different from the SI unit for magnetic flux density (B), which is the tesla (T). H and B are related, but they represent different aspects of a magnetic field. The magnetic field strength (H) is concerned with how much magnetizing force is provided to create a magnetic field, while the magnetic flux density (B) describes the density of the magnetic field lines in a given area.
Magnetic flux, represented by the symbol Ø, has the SI unit of weber (Wb), which is equivalent to T · m² (tesla times square meter). Any change in magnetic flux induces an electromotive force (emf), which is the principle behind electromagnetic induction.
