Magnetic gravel

While we were walking along the canal this afternoon one of my children was using a magnet to find 'treasure' - such as old nails and the like.
Something surprising happened when we reached the wide gravel path on the west side of the Leamington Lift Bridge (see place on Google maps) - the gravel stuck to the magnet. This happened all the way between the Leamington Bridge and the Viewforth Bridge (we didn't try elsewhere). I'd love to hear theories about why this might be.
