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. WebAdd a comment. 1. Generally, the curl of a vector field v → in R 3 is given by, ∇ × v → = ( ∂ y v z − ∂ z v y ∂ z v x − ∂ x v z ∂ x v y − ∂ y v x) which may be viewed mathematically as simply the cross product of the field with …
