## Main Question or Discussion Point

Can someone help me intuitively understand why if a field has zero curl then it must be the gradient of a scalar potential?

Thanks!

If the curl is zero the field does not rotate so the field lines look like gradient flows.Can someone help me intuitively understand why if a field has zero curl then it must be the gradient of a scalar potential?

Thanks!
