I have various brushed aluminium surfaces in my flat: an oven, a hob, a metal angle poise lamp, a stereo and some lightswitches. If I brush my fingers very gently along the metal there is a strange vibrating sensation that is only apparent when I move my finger. If I keep moving my finger the sensation continues.
This sensation disappears if I turn of the power to these items.
I just visited House of Fraser and John Lewis and a lot of their brushed aluminium lights and stereos with aluminium fronts also do this.
I went into Ryness who are an electrical supplier and some of their lights also do it.
I am therefore assuming that this can't be a problem with my house as these shops must have to be very strictly tested.
Can anybody explain what this sensation is? Static? Something to do with double insulating?
