A changing magnetic field creates an electric field.
This Faraday In- duction Law was discovered experimentally, and can be stated as follows. ( ∇ · J + ∂ρ ∂t ) dV = 0. ∇ × B = µ0J + µ0ϵ0 ∂ E ∂t .
The formula F = (E + v B) tells the relationship between electric and magnetic fields.
In accordance with the constitutive relations, the electric displacement D and magnetic intensity H are related to the electric field and magnetic flux density by the formulas: D= E, B= H.
The magnetic field equation for a wire or the magnitude of magnetic field equation is: B = μ 0 ∗ I 2 ∗ Π ∗ r .
The magnetic field B and the movement of electric charges v create a magnetic force where the magnetic force formula is F → = q ∗ v → × B → .
