I tried all three of them
Mercury itself is diamagnetic (repels magnets) because all of the electrons it has are completely paired up yielding a neutral polarityThe same is also true for LeadAluminum has an unpaired electron in the p-shell this gives it a slight polarity called paramagnetismThe actual forces at work here are very weak and so you have to have a very strong magnetic field for the effect to become apparentContrast this with Cobalt Nickel and Iron who permanently have unpaired electrons and have a very noticeable polarity.
No, a stove top produces hot points Better to just shape the pancakes with the spatula.
It would make more sense to make a pancake and them cut them out with a heart shaped cookie cutterI would not use foil on a burner.it will not turn out wellGood Luck
If you are using a frying pan on a gas stove - yesI fold tin foil into a strongish ribbon then form the shape I want: hearts, gingerbread men, etcMake sure the pan is fairly warm before you put the tin foil shape in remove the shape as soon as the pancake is set, but before you flip itYou can trim the little splashes before servingHOWEVER - there are reusable shapes available at many kitchen supply storesThey are not very expensive are permanent additions to your kitchen.
