    Distance between current-carrying loops

    If I generate current through two identical loops (parallel) of transformer wire in the same direction, why do they produce an uniform magnetic field at the centre of the space between the loops ONLY IF the separation distance between the loops is equal to the radius of each coil? and not if...

    How can a Helmholtz arrangement be used to null out magnetic fluctuations?

    thanks, that's pretty helpful, ok this is what I am planning to do: suspend a rare-earth magnet (small, very strong, neodymium) in a box and attach a small piece of mirror on the magnet, shine a beam of laser light on the mirror. supposedly if the magnets are strong enough, it can interact with...

    How can a Helmholtz arrangement be used to null out magnetic fluctuations?

    hey I am pretty sure that if the right amount of current passes through the pair of coils in a helmholtz arrangement, the magnetic field it produces can null out any magnetic fluctuation. but how can you calculate the magnetic field it generates? thanks a lot and correct me if there was any...

    Electricity generated by conductor

    I got a question: when a conductor is charged with current electricity, does it create any kind of magneticism strong enough to affect the present magnetic field, and how do you calculate the amount of magneticism generated? thanks a lot

    Peanut Butter & Bread: Is It Enough For Long-Term Nutrition?

    yeah it would keep you alive, but healthy? I highly doubt it. as matthyaouw said, bread contains lots of carbohydrates, which are an essential part of your diet (should always account for 50% of diet), and your brain consumes a lot of glucose - a form of carbohydrates. but peanut butter contains...
