摘要：

Based　on　COMSOL　software　simulation　analysis　was　carried　out　on　the　magnetic　field　for　degaussing　hard　drive.　Firstly,　the　magnetic　field　intensity　of　the　solenoid　coil　with　finite　length　is　calculated.　Then,　the　three-dimensional　numerical　solution　of　the　magnetic　field　intensity　of　the　solenoid　coil　is　obtained　by　using　COMSOL　software　simulation　model.　The　comparison　and　analysis　prove　the　consistency　of　the　two.　Further　simulations　show　that　the　effective　influencing　factors　of　the　demagnetizing　magnetic　field　strength　include　current　density,　coil　height　and　form.　©　2019　IEEE.
