Patent ID: 8421569

Claim:
A magnetic field generator, comprising: a holding unit; an induction winding slidably and rotatably mounted on the holding unit; and an operation unit electrically connected to the induction winding, and positioned in a predetermined distance away from the induction winding; the operation unit providing current to the induction winding, and the induction winding generating magnetic field in response to receiving the current from the operation unit; wherein the holding unit includes an adjusting pole and a support block, the support block defines a first through hole and a second through hole, an axis of the first through hole being perpendicular to an axis of the second through hole; the induction winding is inserted into the second through hole to be rotatably mounted on the support block, and the adjusting pole is inserted into the first through hole to be slidably and rotatably mounted on the support block for adjusting an altitude of the induction winding relative to the adjusting pole.
