Hi, All

I am wondering what exactly B field and H field differs?

Magnetic field is very strange
It does not behave the same way as electric one. See, D=uE, we know displacement field for D and electric one for E

Here, we can not use the same idea for magnetic one!

Srsly, how do we understand this abstract field?

Thanks in advance
 

Formally, you have a very similar relation for the magnetic quantities
B = µ*H.
 

Yes, buddy. Sorry about my bad discription. But thanks again.

My question is in fact what is the name of B and H ?

Besides, what is the physical meaning of these two fiedls?

Instead of only the equation, I wonder anyone could tell me sth about the property of the symbols they represent?

Thanks in advance.

Sincelry
 

A physician will most likely tell, that the physical meaning of B and H is clarified in Maxwell's Equations.

A more visual explanation says, that magnetic field strength H is the effect of a circular current (according to Biot-Savart's law) and the change of flux density B is the cause of induced voltage (Faraday's law of induction).
 
Ok, I will check the Maxwell's equation now.

Thanks for your pointing out the meaning of these two fields.
