Claim 14:
15. A method of providing PEMF stimulation to a knee of a user for treatment of osteoarthritis, the method comprising:
wrapping an applicator around a leg of the user such that:
a first multi-turn rectangular coil is disposed above the knee, defining an upper loop and a lower loop around the leg of the user,
a second multi-turn rectangular coil is disposed below the knee, defining an upper loop and a lower loop around the leg of the user, and
a third coil overlays a patella of the knee;

energizing the lower loop of the first coil and the upper loop of the second coil synchronously to generate a magnetic field along the knee in a common direction normal to a tibial plateau of the user, wherein the lower loop of the first coil generates a magnetic field in a first direction while the upper loop of the first coil generates a magnetic field in a second direction that is opposite of the first direction, wherein the upper loop of the second coil generates a magnetic field in a first direction while the lower loop of the second coil generates a magnetic field in a second direction that is opposite of the first direction; and
energizing the third coil to generate a magnetic field normal to the patella.
