### What is magnetic field strength?

The magnetic field can be visualized as magnetic field lin The field strength corresponds to the density of the field lin The total number of magnetic field lines penetrating an area is called the magnetic fluxThe unit of the magnetic flux is the tesla meter squared (T m 2, also called the weber and symbolized Wb)The older units for the magnetic flux, the maxwell (equivalent to 10-8.

### I need help with this physics magnetic field problem

Mar 15, 2011· Lightning bolts can carry currents up to approximately 20 kA We can model such a current as the equivalent of a very long, straight wire If you were unfortunate enough to be 55 m away from such a lightning bolt, how large a magnetic field would you experience?

### Megagauss-level magnetic field production in cm-scale auto

Initially, helical current in the AutoMag liner produces internal axial magnetic field during a long (100 to 300 ns) current prepulse with an average current rise rate dI/dt=5 kA/ns After the cold fuel is magnetized, a rapidly rising current (200 kA/ns) generates a calculated electric field.

### electromagnetism

Taking the curl of the electric field must be possible, because Faraday's law involves it: $$\nabla \times \mathbf{E} = - \partial \mathbf{B} / \partial t$$ But I've just looked on Wikipedia, where it says The curl of the gradient of any twice-differentiable scalar field $\phi$ is always the zero vector: $$\nabla \times (\nabla \phi)=\mathbf{0}$$.
