What are magnetic field lines and how do they represent the information contained within a magnetic vector field?
Magnetic field lines are imaginary lines that provide an alternative way to represent the information contained within a magnetic vector field. The density of the lines indicates the magnitude of the field. The magnetic field is stronger and crowded near the poles of a magnet, while it becomes weaker and the lines become less dense as we move away from the poles.
Explain the mathematical description of the magnetic field as a vector field.
The magnetic field can be mathematically described as a vector field, which is a set of many vectors drawn on a grid. Each vector points in the direction that a compass would point and has a length dependent on the strength of the magnetic force.
Define magnetic field intensity and its representation as vector H.
Magnetic field intensity, also known as magnetic intensity, is represented as vector $H$ and is defined as the ratio of the MMF needed to create a certain Flux Density ($B$) within a particular material per unit length of that material.
In which units is magnetic field intensity measured?
Magnetic field intensity is measured in units of amperes/metre.
What is the relationship between magnetic field strength and flux density within a particular material?
Magnetic field strength, or magnetic field intensity, is defined as the ratio of the MMF needed to create a certain Flux Density ($B$) within a particular material per unit length of that material.
