If I buy a Polar speed sensor, does it include the magnet?

Just looked on Wiggle and a couple of other sites - just says speed sensor + bike mount, no mention of magnet. I know the sensor is a bit useless without the magnet, but given that you can buy the magnets on their own without the sensor, I wondered if this is true of buying the sensor and it not coming with a magnet.
