Question

no two field lines can intersect eachother

Answer 1

yes this is because the magnetic wavelength does not move tangentially and also strength would be extremely small if it would have intersected then

Answer 2

$\red{hey} \\ \pink {yes \: u \: r \: right \: because \: if \: they \: intersect \: their \: will \: be \: more \: than \: one\: direction \: of \: magnitic \: force \: on \: a \: point \: which \: is \: not \: possible}$
