Prove that if r is a commutative ring and n = (a) is a finitely generated ideal, where a = \{a_1,\ldots, a_n\} and each a_n is nilpotent, then n is a nilpotent ideal. deduce that if the nilradical \mathfrak{n}(r) of r is finitely generated then it is a nilpotent ideal

grav forces affect all objects magnetic forces affect magnetic objects and electric currents

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it
