Specification 12.13 · Paper 2
A measure of the strength of a magnetic field, represented by and measured in tesla (T), equivalent to newtons per ampere metre (N/A m).
Revise: Force EquationMagnetic flux density describes the strength of a magnetic field.

Paper 1, Paper 2
A measure of magnetic field strength, represented by and measured in tesla (T).
Revise: Electric motorsMagnetic flux density measures the strength of the field. If a length is given in centimetres, divide it by 100 before using the equation.
Keep force and field strength distinct: force is measured in newtons (N), whereas magnetic flux density is measured in tesla (T).
