SUMMARY

Tesla (T) is the SI unit for measuring magnetic field strength and magnetic induction, while Weber (Wb) measures magnetic flux. The relationship between these units is defined as 1 Wb = 1 T * 1 m², indicating that Weber quantifies the total magnetic field passing through a given area. Additionally, the intensity of the magnetic field is measured in amperes per meter (A/m). Understanding these units is crucial for accurately describing magnetic phenomena in physics and engineering.

Hi, I was curious as to what webers and teslas measure. As I read up on them I was able to speculate that teslas measured a magnetic fields dimensions and webers measured a magnetic fields strength; obviously though, this is a mere speculation: so please correct me if I am mistaken.

Thank you

Tesla is the SI unit for magnetic induction. Weber is for magnetic flux.
 
Tesla is the unit of magnetic field too if I remember correctly.
 
Tesla is a measure of the strength of a magnetic field.

Webers are T/s, or a rate of change of the magnetic field.

Henry is a measure of inductance, which is ohm seconds.

This is a term used sometimes, in a loose manner, when everybody knows what they are talking about and there is no confusion. The proper name is induction of the field, B and is measured in Tesla. The intensity of the magnetic field (H) is measured in A/m.
So the magnetic field can be measured by two quantities and in empty space B is just proportional to H.

Indeed Tesla is the unit for the induction of the field which is a meausre of "strength".

1 Wb = 1T*1m^2.
It measures magnetic flux and not the rate of change of magnetic field. The flux can be defined for both constant and variable fields.

Oh yes I was mistaken. Thanks for the correction.
 
Thank you all for your input, appreciate it.
