Methods

`Jtvec`(m, v[, u])	Computing Jacobian^T multiplied by vector.
`Jvec`(m, v[, u])	Computing Jacobian multiplied by vector
`fields`(m)	Return magnetic potential (u) and flux (B) u: defined on the cell center [nC x 1] B: defined on the cell center [nG x 1]
`getA`(m)	GetA creates and returns the A matrix for the Magnetics problem
`getB0`()	To use getB0 method, SimPEG requires that the survey be specified.
`getRHS`(m)
`projectFields`(u)	This function projects the fields onto the data space.
`projectFieldsDeriv`(B)	This function projects the fields onto the data space.
