Which of the following is a unit of magnetic flux density?
Tesla
Weber
Henry
Farad
Tesla
Magnetic flux density (also called magnetic induction) is the amount of magnetic flux per unit area, measured in Tesla (T). It represents the strength and orientation of a magnetic field at a specific point in space.
Magnetic flux density (also called magnetic induction) is the amount of magnetic flux per unit area, measured in Tesla (T). It represents the strength and orientation of a magnetic field at a specific point in space.
Think of magnetic flux density like the 'crowd density' at a concert; more people (magnetic field lines) crammed into a smaller square meter area results in higher density.
Remember 'Tesla is Tough' (T for Tesla, T for Total field per area).
B=AΦ — where B is flux density, Φ is magnetic flux, and A is area
1 Tesla=1meter2Weber=1A⋅mN — unit equivalence
The Lorentz force law defines the relationship between the force experienced by a moving charge and the magnetic flux density (B). It is mathematically defined as F=q(vimesB). The SI unit Tesla is derived as one Weber per square meter (Wb/m2).
Magnetic flux density is a vector quantity.
The CGS unit for magnetic flux density is the Gauss (1 Tesla=104 Gauss).
MRI machines for medical imaging
Electric motors and transformers
Weber (Wb) is the SI unit of magnetic flux, not flux density.
Henry (H) is the SI unit of inductance.
Farad (F) is the SI unit of capacitance.
A is correct — Tesla is the standard SI unit for measuring magnetic flux density.
Don't confuse flux (Wb) with flux density (Wb/m2 or T). In exams, 'density' always implies dividing by area.
