A faucet includes a spout; a sprayhead that is moveable relative to the spout between a docked position and an undocked position; a magnet associated with the spout and having a bore; and a magnetically responsive collar associated with the sprayhead and moveable relative to the magnet in an axial direction as the sprayhead moves between the docked and undocked positions. In the docked position, magnetic forces between the magnet and the collar attract a center of the collar to align with a center of the magnet in the axial direction with the collar in the bore of the magnet.

1. A faucet, comprising: a spout;a sprayhead that is moveable relative to the spout between a docked position and an undocked position;a magnet associated with the spout and having a bore; anda magnetically responsive collar associated with the sprayhead and moveable relative to the magnet in an axial direction as the sprayhead moves between the docked and undocked positions;wherein in the docked position, magnetic forces between the magnet and the collar align a center of the collar with a center of the magnet in the axial direction with the collar in the bore of the magnet. 2. The faucet of claim 1, wherein the magnetic forces between the magnet and the collar exceed a force resulting from a weight of the sprayhead. 3. The faucet of claim 1, further comprising: a hose extending through a cavity of the spout for carrying fluid, wherein an end of the hose is coupled to the sprayhead; anda counterweight coupled to the hose at a location;wherein the collar is between the end of the hose and the counterweight. 4. The faucet of claim 3, wherein the magnetic forces between the magnet and the collar exceed a force resulting from a weight of the sprayhead and a weight of an unsupported portion of the hose, which are offset by a weight of the counterweight. 5. The faucet of claim 1, wherein in the docked position, the magnetic forces attracting the collar to the magnet in the axial direction are balanced with magnetic forces attracting the collar to the magnet in a direction that is opposite to the axial direction. 6. The faucet of claim 1, wherein in the docked position, the magnet and the collar are not in direct contact. 7. A faucet, comprising: a spout;a sprayhead that is moveable relative to the spout between a docked position and an undocked position;a magnet associated with the spout and having a bore;a magnetically responsive collar associated with the sprayhead and moveable relative to the magnet in an axial direction as the sprayhead moves between the docked and undocked positions; anda retainer for coupling the magnet to the spout, wherein in the docked position, a portion of the retainer is provided between the magnet and the collar;wherein in the docked position, magnetic forces between the magnet and the collar attract a center of the collar to align with a center of the magnet in the axial direction with the collar in the bore of the magnet. 8. The faucet of claim 7, wherein the portion of the retainer includes a wall extending through the bore of the magnet to support the magnet. 9. The faucet of claim 8, further comprising a field expander disposed between the magnet and a flange of the retainer, which extends radially from the wall, wherein the field expander increases the magnetic forces. 10. The faucet of claim 1, further comprising a field expander coupled to the magnet and having a bore that aligns with the bore of the magnet, wherein the field expander increases the magnetic forces. 11. The faucet of claim 10, wherein the collar is disposed in the bore of the field expander and the bore of the magnet in the docked position. 12. A faucet, comprising: a spout;a sprayhead that is moveable relative to the spout between a docked position and an undocked position;a magnet associated with the spout; anda magnetically responsive collar associated with the sprayhead and moveable relative to the magnet in first and second axial directions as the sprayhead moves between the docked and undocked positions;wherein in the docked position, magnetic forces attracting the collar to the magnet in the first axial direction are balanced with magnetic forces attracting the collar to the magnet in the second axial direction that is opposite to the first axial direction. 13. The faucet of claim 12, wherein the magnetic forces between the magnet and the collar exceed a force resulting from a weight of the sprayhead. 14. The faucet of claim 12, further comprising: a hose extending through a cavity of the spout for carrying fluid, wherein the hose is coupled to the sprayhead at an end; anda counterweight coupled to the hose at a location;wherein the collar is between the end of the hose and the counterweight. 15. The faucet of claim 14, wherein the magnetic forces between the magnet and the collar exceed a force resulting from a weight of the sprayhead and a weight of an unsupported portion of the hose, which are offset by a weight of the counterweight. 16. A faucet comprising: a spout;a sprayhead that is rotatable about an axis relative to the spout between a first position and a second position, wherein the sprayhead is moveable along the axis relative to the spout between a docked position and an undocked position;a magnet associated with the spout;a magnetically responsive collar associated with the sprayhead so that the collar rotates and moves with the sprayhead relative to the spout and the magnet; anda field expander provided adjacent to the magnet to increase the magnetic forces, wherein the field expander has a bore that aligns with a bore of the magnet and the collar is disposed in the bores of the field expander and the magnet in the docked position;wherein in the first and docked positions, magnetic poles of the collar are opposite magnetic poles of the magnet such that the collar and magnet are attracted to one another by magnetic forces; andwherein in the second and docked positions, the magnetic poles of the collar are aligned with the magnetic poles of the magnet such that the collar and magnet are repelled from one another by the magnetic forces. 17. The faucet of claim 16, further comprising a retainer for coupling the magnet and the field expander to the spout. 18. The faucet of claim 17, wherein in the docked position, a wall of the retainer is provided between the magnet and the collar. 19. The faucet of claim 16, wherein the magnetic poles of each of the magnet and the collar comprises at least one N pole and at least one S pole.
