WebThe magnetic field is NOT conservative in the presence of currents or time-varying electric fields. A conservative field should have a closed line integral (or curl) of zero. Maxwell's fourth equation (Ampere's law) can be written ∇ × B = μ 0 J + μ 0 ϵ 0 ∂ E ∂ t, so you can see this will equal zero only in certain cases. WebWe can find the magnetic field that is caused by moving charges using a second right-hand rule. The magnetic field made by a current in a straight wire curls around the wire in a ring. You can find it by pointing your right thumb in the direction of the current in the wire and curling your fingers. bipls python
