Magnetic Flux Q&A: Can Length Contraction Alter Quanta?

In summary, the conversation discussed the possibility of altering the quanta of magnetic flux using length contraction and whether the Planck length has any special significance. It was determined that the magnetic flux is a scalar quantity that does not change with Lorentz boosts, and the Planck length is simply a unit of measurement with no special meaning other than its potential impact on space-time at small scales. It was also suggested that length contraction may not have an effect on the minimum length.

Can I alter the quanta of magnetic flux using length contraction of the source creating the B field. Like for example could I get half of the flux by moving relative to the B field. Or some other fraction of it. The unit of flux is like [itex] \frac{h}{2e} [/itex]

The magnetic flux is actually a scalar quantity which doesn't change from Lorentz boosts. This is because while the magnetic field changes, the area also changes in exactly compensating ways.

ok interesting, what about the Planck length
 
  • #4
What about it? It's just a unit of measurement, like the meter. It doesn't really mean anything special except we expect that at those lengths (i.e. order of magnitude near the Planck length), space-time might look different.

If there is a minimum length, then i could just move by it a speed and length contract it.
Or maybe this doesn't matter.
 

1. What is magnetic flux?

Magnetic flux is a measure of the amount of magnetic field passing through a given area. It is represented by the symbol Φ and is measured in units of webers (Wb).

2. How does length contraction affect magnetic flux?

Length contraction is a concept in special relativity where an object's length appears shorter when it is moving at high speeds. This does not directly affect magnetic flux, as it is a measure of the magnetic field passing through a given area and is not dependent on the length of the object.

3. Can length contraction alter quanta?

No, length contraction does not alter quanta. Quanta are discrete units of energy, and their value is not affected by an object's length or speed.

4. How is magnetic flux calculated?

Magnetic flux is calculated by multiplying the magnetic field strength by the area through which it is passing. Mathematically, it is represented as Φ = B x A, where B is the magnetic field strength and A is the area.

5. Is magnetic flux a vector or a scalar quantity?

Magnetic flux is a scalar quantity, meaning it only has magnitude and no specific direction. However, it can be represented by a vector quantity when considering the direction of the magnetic field lines passing through the given area.
