I want to make cheese biscuits, but the recipes calls for cookie sheetsI don't have any of that kind and all I have is aluminum foil [ with butter and/or cooking spray]If not, any other options?
You would be better off with a heavier cooking surfaceThe aluminum foil is pretty thin and the bottom of the biscuits may burnDo you have a roasting pan or cake pan that you can use? (13X9 pan would be perfect.) Move the rack down one level and use the pan inverted so you are cooking on the bottom of the panI suggest moving the rack down one level because the height of the inverted pan will bring the baking surface up the the proper level.
This is very much like a falling object with air resistance reaching terminal velocity as it fallsThis happens because the upwards force (air resistance) increases as speed increasesThe initial air resistance is zero and acceleration gBut as speed increases the air resistance increases and eventually becomes the same magnitude as the object's weightThen we get terminal velocity (air resistance equals the object's weight and acceleration 0)This is just the same for the falling magnetThe upwards force is magnetic, not air resistance but otherwise it’s the same processInitial acceleration gEventually upwards magnetic force equals weight and the magnet will reach a terminal velocity (acceleration falls to zero)Which way round (north/south, top/bottom) makes no difference(NoteCopper works better than aluminium because of the lower resistivity.)
