Kitchen aid blender magnet

I have a KitchenAid blender Model KSB50B4 with a serial number of WS4729749. I broke the magnet on the bottom of the motor and would like to purchase another magnet to replace it but I don’t see that part listed separately. I think it is a speed sensor. How may I order that part? Is it available? Or if not, can I operate the blender without it?

I am also having some problems with my blender. I was thinking of buying a new blender but after I read some reviews at benefits-of-juicing.net/juicer-blender-25-essential-reasons about the comparison between a juicer and a blender. I probably would save myself from the headache it may bring me. Do you think you can give some advice if it is wise to buy a new juicer or try repairing my blender? I am actually using blender for making juices, most of the time. Thanks mate

I guess many of us are facing the same problem
