IB HL Physics Magnetic flux

A tutorial sheet on magnetic flux is given below.

1. Define magnetic flux density.
2. Define magnetic flux.
3. Define one tesla.
4. Define one weber.
5. Can the magnetic flux through a coil be increased by increasing the number of turns in the coil?
6. The equation giving the magnetic flux through an area is ϕ = BAcosθ. How is the angle θ defined?
7. Define magnetic flux linkage.
8. Several properties of the magnetic flux are given below. Which are correct and how could these be improved? a) magnetic flux is the amount of magnetic field crossing an area, b) magnetic flux is the number of magnetic field lines crossing an area, c) magnetic flux through a plane area is the product of the area and the sum of all of the perpendicular B components crossing it, d) the magnetic flux through any closed surface is always zero.
